 Microsoft PowerToys is a set of utilities for power users to tune and streamline their Windows experience for greater productivity. Inspired by the [Windows 95 era PowerToys project](https://en.wikipedia.org/wiki/Microsoft_PowerToys), this reboot provides power users with ways to squeeze more efficiency out of the Windows 10 shell and customize it for individual workflows.  A great overview of the Windows 95 PowerToys can be found [here](https://socket3.wordpress.com/2016/10/22/using-windows-95-powertoys/).

+## Localization on the pipeline (CDPX)
+[The localization step](https://github.com/microsoft/PowerToys/blob/86d77103e9c69686c297490acb04775d43ef8b76/.pipelines/pipeline.user.windows.yml#L45-L52) is run on the pipeline before the solution is built. This step runs the [build-localization](https://github.com/microsoft/PowerToys/blob/master/.pipelines/build-localization.cmd) script, which generates resx files for all the projects with localization enabled using the `Localization.XLoc` package.
+
+The [`Localization.XLoc`](https://github.com/microsoft/PowerToys/blob/86d77103e9c69686c297490acb04775d43ef8b76/.pipelines/build-localization.cmd#L24-L25) tool is run on the repo root, and it checks for all occurrences of `LocProject.json`. Each localized project has a `LocProject.json` file in the project root, which contains the location of the English resx file, list of languages for localization, and the output path where the localized resx files are to be copied to. In addition to this, some other parameters can be set, such as whether the language ID should be added as a folder in the file path or in the file name. When the CDPX pipeline is run, the localization team is notified of changes in the English resx files. For each project with localization enabled, a `loc` folder (see [this](https://github.com/microsoft/PowerToys/tree/master/src/modules/launcher/Microsoft.Launcher/loc) for example) is created in the same directory as the `LocProject.json` file. The folder contains language specific folders which in turn have a nested folder path equivalent to `OutputPath` in the `LocProject.json`. Each of these folders contain one `lcl` file. The `lcl` files contain the English resources along with their translation for that language. These are described in more detail [here](#lcl-files). Once the `.resx` files are generated, they will be used during the `Build PowerToys` step for localized versions of the modules.

+Since the localization script requires certain nuget packages, the [`restore-localization`](https://github.com/microsoft/PowerToys/blob/master/.pipelines/restore-localization.cmd) script is run before running `build-localization` to install all the required packages. This script must [run in the `restore` step](https://github.com/microsoft/PowerToys/blob/86d77103e9c69686c297490acb04775d43ef8b76/.pipelines/pipeline.user.windows.yml#L37-L39) of pipeline because [the host is network isolated](https://onebranch.visualstudio.com/Pipeline/_wiki/wikis/Pipeline.wiki/2066/Consuming-Packages-in-a-CDPx-Pipelinhttps://onebranch.visualstudio.com/Pipeline/_wiki/wikis/Pipeline.wiki/2066/Consuming-Packages-in-a-CDPx-Pipeline?anchor=overview) at the `build` step. The [Toolset package source](https://github.com/microsoft/PowerToys/blob/86d77103e9c69686c297490acb04775d43ef8b76/.pipelines/pipeline.user.windows.yml#L23) is used for this.
+
+The process and variables that can be tweaked on the pipeline are described in more detail [here](https://onebranch.visualstudio.com/Pipeline/_wiki/wikis/Pipeline.wiki/290/Localization).
+
+The localized resource dlls for C# projects are added to the MSI only for build on the pipeline. This is done by checking if the [`IsPipeline` variable is defined](https://github.com/microsoft/PowerToys/blob/f92bd6ffd38014c228544bb8d68d0937ce4c2b6d/installer/PowerToysSetup/Product.wxs#L804-L805), which gets defined before building the installer on the pipeline [here](https://github.com/microsoft/PowerToys/blob/f92bd6ffd38014c228544bb8d68d0937ce4c2b6d/.pipelines/build-installer.cmd#L4). This is done because the localized resx files are only present on the pipeline, and not having this check would result in the installer project failing to build locally.
+
+### UWP Special case
+C# projects normally expect localized resource files with the language id in the file name as Resources.`langId`.resx, where `langId` is generally a two character code except for language with specific variants (like zh-Hans or pt-BR):
+
+For example, `path\Resources.resx` for English and `path\Resources.fr.resx` for French.
+
+UWP differs from this as it expects the resources to have the same Resources.resw file name, but they should be present in language specific folders, with the full language ID (such as fr-fr, zh-hans, pt-br, etc.)
+
+For example, `path\en-us\Resources.resw` for English and `path\fr-fr\Resources.resw` for French.
+
+Since the pipeline generates it in this format, [a script is run](https://github.com/microsoft/PowerToys/blob/86d77103e9c69686c297490acb04775d43ef8b76/.pipelines/build-localization.cmd#L29-L31) to move these resw files to the correct format expected by all UWP projects. Currently the only UWP project is [Microsoft.PowerToys.Settings.UI](https://github.com/microsoft/PowerToys/tree/master/src/core/Microsoft.PowerToys.Settings.UI). The script used for moving the resources can be [found here](https://github.com/microsoft/PowerToys/blob/master/tools/localization/move_uwp_resources.ps1). The equivalent full language IDs for each shortened language ID obtained from the pipeline has been hardcoded in the script.
+
+## Enabling localization on a new project
+To enable localization on a new project, the first step is to create a file `LocProject.json` in the project root.
+
+For example, for a project in the folder `src\path` where the resx file is present in `resources\Resources.resx`, the LocProject.json file will contain the following:
+```
+{
+    "Projects": [
+        {
+            "LanguageSet": "Azure_Languages",
+            "LocItems": [
+                {
+                    "SourceFile": "src\\path\\resources\\Resources.resx",
+                    "CopyOption": "LangIDOnName",
+                    "OutputPath": "src\\path\\resources"
+                }
+            ]
+        }
+    ]
+}
+```
+The rest of the steps depend on the project type and are covered in the sections below. The steps to add the localized files to the MSI can be found [here](#Enabling-localized-MSI-for-a-new-project).
+
+### C++
+C++ projects do not support `resx` files, and instead use `rc` files along with `resource.h` files. The CDPX pipeline however doesn't support localizing `rc` files and the other alternative they support is directly translating the resources from the binary which makes it harder to maintain resources. To avoid this, a custom script has been added which expects a resx file and converts the entries to an rc file with a string table and adds resource declarations to a resource.h file so that the resources can be compiled with the C++ project.
+
+If you already have a .rc file, copy the string table to a separate txt file and run the [convert-stringtable-to-resx.ps1](https://github.com/microsoft/PowerToys/blob/master/tools/build/convert-stringtable-to-resx.ps1) script on it. This script is not very robust to input, and requires the data in a specific format, where `IDS_ResName L"ResourceValue"` and any number of spaces can be present in between. The script converts this file to the format expected by [`resgen`](https://docs.microsoft.com/en-us/dotnet/framework/tools/resgen-exe-resource-file-generator#Convert), which will convert it to resx. The resource names are changed from all uppercase to title case, and the `IDS_` prefix is removed. Escape characters might have to be manually replaced, for example .rc files would have escaped double quotes as `""`, so this should be replaced with just `"` before converting to the resx files.
+
+After generating the resx file, rename the existing rc and h files to ProjName.base.rc and resource.base.h. In the rc file remove the string table which is to be localized and in the .h file remove all `#define`s corresponding to localized resources. In the vcxproj of the C++ project, add the following build event:
+```
+<Target Name="GenerateResourceFiles" BeforeTargets="PrepareForBuild">
+    <Exec Command="powershell -NonInteractive -executionpolicy Unrestricted $(SolutionDir)tools\build\convert-resx-to-rc.ps1 . resource.base.h resource.h ProjName.base.rc ProjName.rc" />
+</Target>
+```
+
+This event runs a script which generates a resource.h and ProjName.rc in the `Generated Files` folder using the strings in all the resx files along with the existing information in resource.base.h and ProjName.base.rc. The script can be found [here](https://github.com/microsoft/PowerToys/blob/master/tools/build/convert-resx-to-rc.ps1). The script uses [`resgen`](https://docs.microsoft.com/en-us/dotnet/framework/tools/resgen-exe-resource-file-generator#Convert) to convert the resx file to a string table expected in the .rc file format. When the resources are added to the rc file the `IDS_` prefix is added and resource names are in upper case (as it was originally). Any occurrences of `"` in the string resource is escaped as `""` to prevent build errors. The string tables are added to the rc file in the following format:
+```
+#if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_ENU)
+LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
+
+STRINGTABLE
+BEGIN
+    strings
+END
+
+#endif
+```
+Since there is no API to identify the `AFX_TARG_*`, `LANG_*` or `SUBLANG_*` values from each langId from the pipeline, these are hardcoded in the script (for each language) as done [here](https://github.com/microsoft/PowerToys/blob/f92bd6ffd38014c228544bb8d68d0937ce4c2b6d/tools/build/convert-resx-to-rc.ps1#L50-L77). **If any other languages are added in the future, this script will have to be updated.** In order to determine what are the language codes, you can open the rc file in Resource View, right click the string table and press `Insert Copy` and choose the corresponding language. This autogenerates the required code and can be used to figure out the language codes. The files also add the resource declarations to a resource.h file, starting from 101 by default(this can be changed by an optional argument). Since the output files will be generated in `Generated Files`, any includes in these two files will require an additional `..\` and wherever resource.h is used, it will have to be included as `Generated Files\resource.h`. While adding `resource.base.h` and `ProjName.base.rc` to the vcxproj, these should be modified to not participate in the build to avoid build errors:
+```
+<None Include="Resources.resx" />
+```
+
+Some rc/resource.h files might be used in multiple projects (for example, KBM). To ensure the projects build for these cases, the build event can be added to the entire directory so that the rc files are generated before any project is built. See [Directory.Build.targets](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/Directory.Build.targets) for an example.
+
+Check [this PR](https://github.com/microsoft/PowerToys/pull/6104) for an example for making these changes for a C++ project.
+
+### C#
+Since C# projects natively support `resx` files, the only step required here is to include all the resx files in the build. For .NET Core projects this is done automatically and the .csproj does not need to be modified. For other projects, the following line needs to be added:
+```
+<EmbeddedResource Include="Properties\Resources.*.resx" />
+```
+
+**Note:** Building with localized resources may cause a build warning `Referenced assembly 'mscorlib.dll' targets a different processor` which is a VS bug. More details can be found [here](https://github.com/microsoft/PowerToys/issues/7269).
+
+**Note:** If a project needs to be migrated from XAML resources to resx, the easiest way to convert the resources would be to change to format to `=` separates resources by either manually (by Ctrl+H on a text editor), or by a script, and then running [`resgen`](https://docs.microsoft.com/en-us/dotnet/framework/tools/resgen-exe-resource-file-generator#Convert) on `Developer Command Prompt for VS` to convert it to resx format.
+```
+<system:String x:Key="wox_plugin_calculator_plugin_name">Calculator</system:String>
+<system:String x:Key="wox_plugin_calculator_plugin_description">Allows to do mathematical calculations.(Try 5*3-2 in Wox)</system:String>
+<system:String x:Key="wox_plugin_calculator_not_a_number">Not a number (NaN)</system:String>
+```
+to
+```
+wox_plugin_calculator_plugin_name=Calculator
+wox_plugin_calculator_plugin_description=Allows to do mathematical calculations.(Try 5*3-2 in Wox)
+wox_plugin_calculator_not_a_number=Not a number (NaN)
+```
+After adding the resx file to the project along with the resource generator, references to the strings will have to be replaced with `Properties.Resources.resName` rather than the custom APIs. Check [this PR](https://github.com/microsoft/PowerToys/pull/6165) for an example of the changes required.
+
+### UWP
+UWP projects expect `resw` files rather than `resx` (the format is almost the same). Unlike other C# projects, the files are expected in the format `fullLangId\Resources.resw`. To include these files in the build, replace the following line in the csproj:
+```
+<PRIResource Include="Strings\en-us\Resources.resw" />
+```
+to
+```
+<PRIResource Include="Strings\*\Resources.resw" />
+```
+
+## Lcl Files
+Lcl files contain all the resources that are present in the English resx file, along with a translation if it has been added.
+
+For example, an entry for a resource in the lcl file looks like this:
+```
+<Item ItemId=";EditKeyboard_WindowName" ItemType="0;.resx" PsrId="211" Leaf="true">
+    <Str Cat="Text">
+        <Val><![CDATA[Remap keys]]></Val>
+        <Tgt Cat="Text" Stat="Loc" Orig="New">
+            <Val><![CDATA[Remapper des touches]]></Val>
+        </Tgt>
+    </Str>
+    <Disp Icon="Str" />
+</Item>
+```
+The `<Tgt>` element would not be present in the initial commits of the lcl files, as only the English version of the string would be present.
+
+**Note:** The CDPX Localization system has a fail-safe check on the lcl files, where if the English string value which is present inside `<Val><![CDATA[*]]></Val>` does not match the value present in the English Resources.resx file then the translated value will not be copied to the localized resx file. This is present so that obsolete translations would not be loaded when the English resource has changed, and the English string will be used rather than the obsolete translation.
+
+## Possible Issues in localization PRs (LEGO)
+Since the LEGO PRs update some of the strings in LCL files at a time, there can be multiple PRs which modify the same files, leading to merge conflicts. In most cases this would show up on GitHub as a merge conflict, but sometimes a bad git merge may occur, and the file could end up with incorrect formatting, such as two `<Tgt>` elements for a single resource. These can be fixed by ensuring the elements follow the format described in [this section](#lcl-files). To catch such errors, the build farm should be run for every LEGO PR and if any error occurs in the localization step, we should check the corresponding resx/lcl files for conflicts.
+
+## Enabling localized MSI for a new project
+For C++ and UWP projects no additional files are generated with localization that need to be added to the MSI. For C++ projects all the resources are added to the dll/exe, while for UWP projects they are added to the `resources.pri` file (which is present even for an unlocalized project). To verify if the localized resources are added to the `resources.pri` file the following steps can be done:
+- Open `Developer Command Prompt for VS`
+- After navigating to the folder containing the pri file, run the following command:
+
+        makepri.exe dump /if .\resources.pri
+- Check the contents of the `resources.pri.xml` file that is generated from the command. The last section of the file will contain the resources with the strings in all the languages:
+```
+<NamedResource name="GeneralSettings_RunningAsAdminText" uri="ms-resource://f4f787a5-f0ae-47a9-be89-5408b1dd2b47/Resources/GeneralSettings_RunningAsAdminText">
+    <Candidate qualifiers="Language-FR" type="String">
+        <Value>Running as administrator</Value>
+    </Candidate>
+    <Candidate qualifiers="Language-EN-US" isDefault="true" type="String">
+        <Value>Running as administrator</Value>
+    </Candidate>
+</NamedResource>
+```
+
+For C# projects, satellite dlls are generated when the project is built. For a project named `ProjName`, files are created in the format `langId\ProjName.resources.dll` where `langId` is in the same format as the lcl files. The satellite dlls need to be included with the MSI, but they must be added only if the solution is built from the build farm, as the localized resx files will not be present on local machines (and that could cause local builds of the installer to fail).
+This can be done by adding the directory name of the project [here](https://github.com/microsoft/PowerToys/blob/f92bd6ffd38014c228544bb8d68d0937ce4c2b6d/installer/PowerToysSetup/Product.wxs#L806) and a resource component for the project can be created [here](https://github.com/microsoft/PowerToys/blob/f92bd6ffd38014c228544bb8d68d0937ce4c2b6d/installer/PowerToysSetup/Product.wxs#L845-L847) in this format:
+```
+<Component Id="ProjName_$(var.IdSafeLanguage)_Component" Directory="Resource$(var.IdSafeLanguage)ProjNameInstallFolder">
+    <File Id="ProjName_$(var.IdSafeLanguage)_File" Source="$(var.BinX64Dir)modules\ProjName\$(var.Language)\ProjName.resources.dll" />
+</Component>
+```
+
+We should also ensure the new dlls are signed by the pipeline. Currently all dlls of the form [`*.resources.dll` are signed](https://github.com/microsoft/PowerToys/blob/f92bd6ffd38014c228544bb8d68d0937ce4c2b6d/.pipelines/pipeline.user.windows.yml#L68).
+
+**Note:** The resource dlls should be added to the MSI project only after the initial commit with the lcl files has been done by the Localization team. Otherwise the pipeline will fail as there wouldn't be any resx files to generate the dlls.

+## HandleSingleKeyRemapEvent
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L13-L124) is used for handling the key to key and key to shortcut remapping logic. The general logic is as follows:
+- Check if the `dwExtraInfo` field contains the `KEYBOARDMANAGER_INJECTED_FLAG` bit set. This bit is used to indicate that the key event was generated by KBM using `SendInput`. This ensures that we don't read events generated by the key or shortcut remap methods.
+- Check if the current key is present in the list of remaps. If it isn't, return 0 (i.e. do not suppress the event).
+- If it is remapped to Disable, suppress the event.
+- If it is remapped to a key, we send the key down/up message for the target key and suppress the current key event. We have a check for filtering artificial keys, such as `VK_WIN` (which is a keycode added by us), so that it is translated to `VK_LWIN` instead.
+- If it is remapped to a shortcut, for key down we set the target modifiers first, followed by the target action key, and for key up we release the action key first, followed by the modifiers.
+- All the remapped key events that we send above are sent with `KEYBOARDMANAGER_SINGLEKEY_FLAG` on the `dwExtraInfo` field.
+
+## HandleShortcutRemapEvent
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L178-L739) is used for handling the shortcut to shortcut and shortcut to key remapping logic. The general logic is as follows:
+- Check if any shortcut remap is currently invoked. This is required to ensure that two remaps don't occur simultaneously at a time, and we send key up events for the shortcuts only if they are actually invoked and not for artificial key up events. In addition to that, while a remap is in the middle of execution, the keyboard state will not match the physical keys, so we do not want a remap <kbd>Ctrl+A</kbd> to <kbd>Ctrl+V</kbd> to also trigger the remap from <kbd>Ctrl+V</kbd> to <kbd>Alt+V</kbd> on pressing <kbd>Ctrl+A</kbd> on the keyboard.
+- Get the remap table as per the the `activatedApp` argument (i.e. if it is empty, we get the global shortcut remap table and otherwise we get the corresponding app-specific shortcut remap table).
+- Iterate over the list of remaps in descending order of number of keys in the shortcut. This is required **for shortcut to key remaps** to ensure that if a user has both <kbd>Ctrl+A</kbd> and <kbd>Ctrl+Shift+A</kbd> remapped to some keys, and the user presses <kbd>Ctrl+Shift+A</kbd>, then we prefer the <kbd>Ctrl+Shift+A</kbd> remap. This logic would not be required if there were only shortcut to shortcut remaps, as they are invoked only on exact match.
+- If any shortcut was found to be invoked (from the first step), then we skip till we find the matching shortcut remap. If not we check if the modifiers of the original shortcut are pressed down. If they are, we check if the current key event is a key down event and it matches the action key of the original shortcut. For shortcut to shortcut and for disabling a shortcut [we have an additional step](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L208-L212) where we check if any other key is pressed apart from the original shortcut. This is required because for these two features we allow the remaps only if those exact keys are pressed. The method used for this is described in detail [here](keyboardmanagercommon.md#IsKeyboardStateClearExceptShortcut). If a win key was pressed, we store whether it was the left or the right one, in order to determine which key to set for remaps from/to the common Win key code which we added. This is so that pressing and releasing Left Win key results in that Win key getting modified and not the Right Win key.
+    - If the remap is to a key, we send a dummy key event followed by releasing the original shortcut's modifiers and setting the target key (or doing nothing if it is remapped to disable) and we suppress the event.
+    - If the remap is to a shortcut, if the modifiers in the original shortcut are present in the target, we only set the additional modifiers and the action key of the target. If it isn't, we send a dummy key event followed by releasing the modifiers which are not common, and setting the remaining ones in the target along with the action key.
+    - For both cases, we set the `isShortcutInvoked` flag to true, and set the `KeyboardManagerState.activatedApp` if it is an app-specific shortcut remap.
+- For the `isShortcutInvoked` is true scenario (i.e. the initial remap keydown section is done) there are several cases depending on the key pressed or released:
+    - [**Case 1:**](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L339-L430) If a modifier in the original shortcut is released, we need to reset back to the physical keys pressed.
+        - For remap to shortcut, we release the target action key if it is currently pressed, and depending on whether all the modifiers of the original shortcut are present in the target, we release the target modifiers that are not common, and set the remaining original shortcut modifiers except the one that was released. We do not need to send the original action key as that will get generate it's own key event if it is held down.
+        - For remap to key, we release the target key if it is pressed (and it is not remapped to Disable), and we set the original shortcut modifiers.
+        - For both the cases we send a dummy key event at the end, since we are setting modifiers without any other key after that, and we reset all the remap variables.
+    - [**Case 2:**](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L435-L461) If the original shortcut's action key is pressed again, we send the target shortcut's action key or the target key again (or for disable we just suppress the event).
+    - [**Case 3:**](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L463-L527) If the original shortcut's action key is released
+        - For remap to shortcut, we just release the target shortcut's action key
+        - For remap to disable, we suppress the event
+        - For remap to key, we check if any other keys are pressed apart from the target key. If not, we just release the target key. If there are, we reset back to the physical keys by releasing the target key and setting the original shortcut's modifiers along with a dummy key, and we reset all the remap variables. This behavior is different from remap to shortcut because if the action key is released while other keys are pressed the remap should be inactive, but such a state can't occur for shortcut to shortcut remaps since they happen only when the exact keys are pressed.
+    - [**Case 4:**](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L529-L551) If a modifier in the original shortcut is pressed, suppress the event
+    - [**Case 5:**](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L553-L732) If any other key is pressed
+        - For remap to shortcut, we need to reset back to physical keys as the shortcut remaps can't be pressed in combination with other keys. We release the target action key if it was pressed, and we release the modifier keys of the target shortcut that are not common and set the remaining ones in the original shortcut. We then send the original shortcut's action key if the target action key was found to be pressed, and we send the current key press at the end.
+        - For remap to key, if it is remapped to disable or if the target key is not found to be pressed, we reset to the physical keys, we set the original shortcut's modifiers and if is remap to Disable and the original shortcut's action key is physically pressed (this is checked by the `isOriginalActionKeyPressed` flag which we keep track of whenever the action key is pressed or released for remap to Disable), then we set the original shortcut's action key, followed by the current key press. If it is not remapped to disable and the target key is pressed, then we don't suppress the event as we allow shortcut to key remappings to be pressed along with other keys.
+        - For all the above cases, dummy key isn't required as we want the current key press to behave like a normal key.
+    - [**Case 6:**](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L733) If any other key is released, do not suppress the event as this event didn't appear with a corresponding key down event (such as an app sending a key up event) or we processed the key down and let it continue (for shortcut to key scenario).
+- All the remapped key events that we send above are sent with `KEYBOARDMANAGER_SHORTCUT_FLAG` on the `dwExtraInfo` field, except the usage of the current key press in Case 5, for which we don't send any extra info so that it is considered as a normal key event which may in turn invoke some other remap.
+
+**Note:** Shortcuts are considered valid if they have modifiers and an action key. The reason why we haven't supported key combinations of just modifiers (which is requested in this [issue](https://github.com/microsoft/PowerToys/issues/5670)) (like remapping <kbd>Ctrl+Alt</kbd>) is because this would require more cases and handling as these remappings have to take place only on press and release and if there is no key pressed in between similar to what Start Menu does. The remapping would have to be invoked only for this specific sequence <kbd>Ctrl</kbd> key down, <kbd>Alt</kbd> key down, <kbd>Alt</kbd> key up, <kbd>Ctrl</kbd> key up (ordering between Ctrl and Alt can be swapped). If any other key is pressed in between it shouldn't be invoked, and since this logic requires tracking exact states instead of using GetAsyncKeyStates, this could cause false positives if a user is not running as admin.
+
+## HandleOSLevelShortcutRemapEvent
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L741-L752) is used for handling global shortcut to shortcut and shortcut to key remaps. The general logic is as follows:
+- Check if the `dwExtraInfo` field is set to `KEYBOARDMANAGER_SHORTCUT_FLAG`. This indicates that the key event was generated by the KBM shortcut remap method using `SendInput`. This ensures that we don't read events generated by the shortcut remap method, but we still read events which are generated by the key remap method.
+- Call `HandleShortcutRemapEvent` without the `activatedApp` argument so that global shortcut remapping takes place if it applies for the current key event.
+
+## HandleAppSpecificShortcutRemapEvent
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L754-L809) is used for handling app-specific shortcut to shortcut and shortcut to key remaps. The general logic is as follows:
+- Check if the `dwExtraInfo` field is set to `KEYBOARDMANAGER_SHORTCUT_FLAG`. This indicates that the key event was generated by the KBM shortcut remap method using `SendInput`. This ensures that we don't read events generated by the shortcut remap method, but we still read events which are generated by the key remap method.
+- Get the name of the process in the foreground. This is done using `GetCurrentApplication` which uses `GetForegroundWindow` to get the window handle and `get_process_path` from the common lib. This approach can fail for UWP apps in full screen, so for that scenario we use the `GetGUIThreadInfo` approach to find the correct window handle, and hence the correct process name. This method is described in more detail [here](keyboardmanagercommon.md#Foreground-app-detection)
+- By checking `KeyboardManagerState.GetActivatedApp` we check if an app-specific shortcut is currently invoked. If so, we consider this application to be the activated app. This is required because some shortcut remaps could cause the current app to lose focus and hence until the shortcut is completely released we should allow that remap to continue, otherwise the user could end up in a state where some keys do not get released. For example: remap <kbd>Ctrl+A</kbd> to <kbd>Alt+Tab</kbd> for Edge, when a user presses <kbd>Ctrl+A</kbd> the window loses focus as <kbd>Alt+Tab</kbd> gets executed.
+- If there is no app-specific shortcut currently invoked, we check if the foreground process is present in the list of app-specific remaps, either with or without the file extension and case insensitive. If it is, this is considered to be the activated app.
+- Call `HandleShortcutRemapEvent` with the `activatedApp` argument so that app-specific shortcut remapping takes place if it applies for the current key event.
+
+## HandleSingleKeyToggleToModEvent (Obsolete - Code from PoC which is commented out)
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L126-L176) was added to support a feature for converting the behavior of a key from behaving like a toggle (like Caps Lock/Num Lock) to a modifier (like Ctrl), such that when you hold Caps Lock it would behave as if Caps Lock was active, and when it was not pressed Caps Lock would be off. For Caps Lock this would be similar to behaving like Shift, but for Num Lock there is no existing key which can substitute for this. This was added while testing out remapping for the KBM PoC, but wasn't added as a feature since it wasn't a priority.
+
+## Tests
+In order to test the remapping logic, a mocked keyboard input handler had to be created because otherwise the tests would process and send actual key events. For this the [`InputInterface`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/InputInterface.h) was made, and in production code the methods are implemented using [`SendInput`](https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-sendinput) and [`GetAsyncKeyState`](https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getasynckeystate). In addition to this, [`GetCurrentApplication`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L226-L268) had to be mocked so that app-specific remapping can be tested.
+
+### MockedInput
+The [`MockedInput`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/MockedInput.h) class uses a 256 size `bool` vector to store the key state for each key code. Identifying the foreground process is mocked by simply setting and getting a string value for the name of the current process.
+
+[To mock the `SendInput` method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/test/MockedInput.cpp#L10-L110), the steps for processing the input are as follows. This implementation is based on public documentation for SendInput and the behavior of key messages and keyboard hooks:
+- Iterate over all the inputs in the INPUT array argument
+- If the event is a key up event, then it is considered [`WM_SYSKEYUP`](https://docs.microsoft.com/en-us/windows/win32/inputdev/wm-syskeyup) if Alt is held down, otherwise it is `WM_KEYUP`.
+- If the event is a key down event, then it is considered [`WM_SYSKEYDOWN`](https://docs.microsoft.com/en-us/windows/win32/inputdev/wm-syskeydown) if either Alt is held down or if it is F10, otherwise it is `WM_KEYDOWN`.
+- An optional function which can be set on the `MockedInput` handler can be used to test for the number of times a key event is received by the system with a particular condition using [`sendVirtualInputCallCondition`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/test/MockedInput.cpp#L48-L52).
+- The hook logic for a low level hook which returns 0 or 1 can be set on the `MockedInput` handler such that it behaves like a low level hook would behave with actual keyboard input. If the method returns 1, then the keyboard state is not updated, and if it returns 0 the corresponding key event is used to update the key state. This works in the recursive way as well similar to low level hooks, as `SendVirtualInput` can be called from within the hook, thus simulating identical behavior to calling `SendInput` in a low level hook (as soon as SendInput is called, the low level hook is called for the new input event, and only after those are processed it returns back to the current event, check this [blog](https://devblogs.microsoft.com/oldnewthing/20140213-00/?p=1773) for more details).
+- For updating the keyboard state, KEYUP messages result in the state for that key code being set to false, and KEYDOWN result in the state for that key code being set to true.
+- For modifiers the behavior is slightly different as if the key state of the L/R version is modified, it should also modify the common version, and if a common version is released, it should release both the L and R versions.
+
+### Tests for single key remaps and shortcut remaps
+Using the MockedInput handler, all the expected (and known) key scenarios that can occur for while pressing a [remapped key](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/SingleKeyRemappingTests.cpp) or [remapped shortcut](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/OSLevelShortcutRemappingTests.cpp) are tested. The foreground app behavior which is specific to app-specific shortcuts is tested [here](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/AppSpecificShortcutRemappingTests.cpp).

+## Class members
+The `KeyboardManager` module has [3 main class members](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L54-L61):
+- A static pointer to the current object of `KeyboardManager`. This is required for using the `KeyboardManager` object in the low level keyboard hook handler as that method must be static. This is described in more detail in [this section](#Low-level-keyboard-hook-handler).
+- An object of type `Input`, which is used for all the operations that involving getting or setting keyboard states. This is wrapped in an object to allow testing the remapping methods.
+- An object of type `KeyboardManagerState`. This object contains all the data related to remappings and is also used in the sense of a View Model as it used to communicate common data that is shared between the KBM UI and the backend. This class is described in more detail [here](keyboardmanagercommon.md#keyboardmanagerstate).
+
+## Enable/Disable
+On enabling KBM, the low level keyboard hook is started, and it is unhooked on disable. This is done to allow users to manually restart KBM if some other application which registers a keyboard hook was launched after PowerToys, so that it can be brought back to the highest priority hook (as the last hook to be registered receives the input first as mentioned [here](https://docs.microsoft.com/en-us/windows/win32/winmsg/about-hooks#hook-procedures)).
+
+In addition to stopping the hook, any active KBM UI windows are also closed on disabling. This is done because the KBM UI uses the same keyboard hook for the Type button where you can type a key/shortcut, so if KBM is disabled the windows would not be completely functional.
+
+The enable/disable code can be found [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L301-L322)
+
+## Settings format
+KBM uses two sets of settings files. 
+- The main `settings.json` is of the following format:
+
+        {
+            "properties":
+            {
+                "activeConfiguration":
+                {
+                    "value":"default"
+                },
+                "keyboardConfigurations":
+                {
+                    "value":["default"]
+                }
+            },
+            "name":"Keyboard Manager",
+            "version":"1"
+        }
+
+    - The `activeConfiguration` attribute stores the current remapping profile, while `keyboardConfigurations` stores all the profiles that the user has. This was added to avoid any future breaking changes for the [profiles feature](https://github.com/microsoft/PowerToys/issues/1881), which would allow users to switch between remappings
+- The profile format (`default.json`) is of the following format:
+
+        {
+            "remapKeys":
+            {
+                "inProcess":
+                [
+                    {
+                        "originalKeys":"91",
+                        "newRemapKeys":"162;70"
+                    },
+                    {
+                        "originalKeys":"92",
+                        "newRemapKeys":"162;70"
+                    }
+                ]
+            },
+            "remapShortcuts":
+            {
+                "global":
+                [
+                    {
+                        "originalKeys":"164;37",
+                        "newRemapKeys":"162;65"
+                    },
+                    {
+                        "originalKeys":"162;68",
+                        "newRemapKeys":"91"
+                    }
+                ],
+                "appSpecific":
+                [
+                    {
+                        "originalKeys":"91;162;65",
+                        "newRemapKeys":"162;86",
+                        "targetApp":"msedge"
+                    }
+                ]
+            }
+        }
+
+    - `originalKeys` stores the key/shortcut which is to be pressed for the remap, and `newKeys` stores the key/shortcut which is to be executed.
+    - Both contain semi-colon separated virtual key codes. For `remapKeys`, `originalKeys` must have only one key code, whereas for `remapShortcuts` it must have atleast two key codes.
+    - `inProcess` sub-key was added in `remapKeys` because there was a possibility of adding the registry based remapping approach (used by [SharpKeys](https://github.com/randyrants/sharpkeys)), so that would be under a separate sub-key while `inProcess` would be for keyboard hook based remaps. This was deprioritized as there weren't enough requests for it.
+    - `remapShortcuts` is split into `global` and `appSpecific`, where `global` remaps would apply to all applications, whereas `appSpecific` would apply on when the `targetApp` is in focus. `targetApp` must be the process name of the app (with or without it's extension), e.g. `msedge` or `msedge.exe` for Microsoft Edge.
+
+## Loading settings
+KBM settings are loaded only on the C++ side only at start up, in the [constructor](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L67-L68). The settings file may get modified from the KBM UI on applying new remappings, but the the file is not read again. The files are read from the PowerToys Settings process whenever a change is made to the file (using a FileWatcher) or whenever the KBM page is opened. The settings are updated only when the user presses the OK button from either of the Remap Keys or Remap Shortcuts windows. This is described in more detail [here](keyboardmanagerui.md#ok-and-cancel-button).
+
+## Low level keyboard hook handler
+Since the [`hook_proc`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L330-L349) cannot be a member function in the class, this is declared `static` and a `static pointer` to the `KeyboardManager` project is used ([`keyboardmanager_object_ptr`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L54-L55)).
+
+As seen in the code for `hook_proc`, similar to other keyboard hooks in PowerToys it consists of a main method `HandleKeyboardHookEvent` which computes whether the key needs to be suppressed and accordingly returns 1 or calls the `CallNextHook` method.
+
+`HandleKeyboardHookEvent` is covered in the [next section](#HandleKeyboardHookEvent). The `SetNumLockToPreviousState` code in the above snippet is required for a special scenario with keyboard input, which is covered in [this section](#Suppressing-Num-Lock-in-a-keyboard-hook).
+
+## HandleKeyboardHookEvent
+The [`HandleKeyboardHookEvent`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L384-L458) is the method which calls the corresponding remapping methods in the required order. The following checks are executed in order:
+- **`KeyboardManagerState.AreRemappingsEnabled`:** This returns false while the KBM remap tables are getting updated. If it is in this state, `HandleKeyboardHookEvent` returns `0`, i.e. the key event is not suppressed and is forwarded normally.
+- **Check for `KEYBOARDMANAGER_SUPPRESS_FLAG`:** If the key event has the suppress flag, the method returns 1 to suppress the key event.
+- **[`KeyboardManagerState.DetectSingleRemapKeyUIBackend`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L399-L408):** This method is used for handling hook operations for the single key Type UI in the Remap keys window. If the Remap keys window is open, then `HandleKeyboardHookEvent` returns `0` and the key event is forwarded normally. If the left column Type button is clicked on the Remap keys window and and the window is in focus, then the key event is suppressed and the UI is updated with the latest key from the recent key events. This method is described in more detail [here](keyboardmanagercommon.md#DetectSingleRemapKeyUIBackend-and-DetectShortcutUIBackend).
+- **[`KeyboardManagerState.DetectShortcutUIBackend(data, true)`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L410-L419):** This method is used for handling hook operations for the shortcut Type UI in the Remap keys window (when `isRemapKey` arg is `true`). If the Remap keys window is open, then `HandleKeyboardHookEvent` returns `0` and the key event is forwarded normally. If the right column Type button is clicked on the Remap keys window and and the window is in focus, then the key event is suppressed and the UI is updated with the shortcut from the recent key events. This method is described in more detail [here](keyboardmanagercommon.md#DetectSingleRemapKeyUIBackend-and-DetectShortcutUIBackend).
+- **`HandleSingleKeyRemapEvent`:** This method handles the single key remap logic. If a remapping takes place, the key event is suppressed. This method is described in more detail [here](keyboardeventhandlers.md#HandleSingleKeyRemapEvent).
+- **[`KeyboardManagerState.DetectShortcutUIBackend(data, false)`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L430-L439):** This method is used for handling hook operations for the shortcut Type UI in the Remap shortcuts window (when `isRemapKey` arg is `false`). If the Remap shortcuts window is open, then `HandleKeyboardHookEvent` returns `0` and the key event is forwarded normally. If the Type button is clicked on the Remap shortcuts window and and the window is in focus, then the key event is suppressed and the UI is updated with the shortcut from the recent key events. **Since this is executed after the single key remap method, all single key remappings are applied when the user is on the Remap shortcuts window.**
+- **`HandleAppSpecificShortcutRemapEvent`:** This method handles the app-specific shortcut remap logic. If a remapping takes place, the key event is suppressed. This method is described in more detail [here](keyboardeventhandlers.md#HandleAppSpecificShortcutRemapEvent). **Since this is executed after the single key remap method, single key remappings have precedence over shortcut remaps and are correspondingly reflected in shortcut remaps.**
+- **`HandleOSLevelShortcutRemapEvent`:** This method handles the global shortcut remap logic. If a remapping takes place, the key event is suppressed. This method is described in more detail [here](keyboardeventhandlers.md#HandleOSLevelShortcutRemapEvent). The app-specific remap method is executed before this because if a shortcut is remapped to different keys/shortcuts for a particular app and globally, the app-specific variant should be preferred if that app is in focus. **Since this is executed after the single key remap method, single key remappings have precedence over shortcut remaps and are correspondingly reflected in shortcut remaps.**
+
+**Note:** Single key remaps need to be executed before shortcut remaps, because otherwise there can be several logical issues. For example if a user has Ctrl remapped to X and Ctrl+A remapped to Y, we can't detect Ctrl+A because the moment Ctrl is pressed it would be remapped to X before the system ever sees Ctrl+A. This is why the design decision was made to separate Remap keys and Remap shortcuts, and all key remaps are reflected in the shortcut remaps.
+
+## Custom Action to launch KBM UI
+KBM uses the [`call_custom_action`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L249-L280) method from the `PowertoyModuleIface` in order to launch the KBM UI when the user clicks the Remap a key or Remap a shortcut button from the KBM settings page. On clicking the button, we check if there is already any active KBM UI window, and if there is it is brought to the foreground. If not, the corresponding KBM UI window is launched on a separate detached thread. The UI is described in more detail [here](keyboardmanagerui.md).
+
+## SendInput Special Scenarios
+
+### Extended keys
+Certain keys such as the arrow keys, <kbd>right Ctrl/Alt</kbd>, and <kbd>Del/Home/Ins</kbd>, etc need to be sent with the `KEYEVENTF_EXTENDEDKEY` flag because otherwise the NumPad versions get sent, which can cause weird behavior when NumLock is on. The code can be found [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L190-L194) and the list of extended keys in code can be found [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L73-L98). Docs about extended keys can be found [here](https://docs.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#extended-key-flag). 
+
+The weird behavior that is caused by this can be found at these issues:
+- https://github.com/microsoft/PowerToys/issues/3478
+- https://github.com/microsoft/PowerToys/issues/3647
+- https://github.com/microsoft/PowerToys/issues/3981
+
+### Scan code
+Certain applications (such as Windows Terminal) may filter out key events which are set to scan code 0. Even though the `KEYEVENTF_SCANCODE` flag is not set, the `wScan` field is still sent, which defaults to 0. To avoid this issue we use the `MapVirtualKey` API to find the scan code from the virtual key code. Code can be found [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L196-L198).
+
+## Special Scenarios
+Since we are using low level keyboard hooks and not actual OS level input handling certain scenarios with input require workarounds as do they not interact well with the OS input logic directly. These are covered in the sub-sections below.
+
+### Dummy key events
+To prevent the behavior that some modifiers have that occur when you press and release the modifier without pressing any key in between, we need to send a dummy key event in between the two states. Some examples of this behavior are Win key for Start Menu and Alt key to focus the menu bar. We need to send the dummy key events at any point where an unintentional modifier press/release sequence may occur. We use the undocumented `0xFF` virtual key code for this as we haven't found any side effects of using this key code yet. Initially we used only a key up message, but it has been tweaked now to send a key down followed by key up (code can be found (here)[https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L201-L208]), as without the key down there were [compatibility issues with some apps](https://github.com/microsoft/PowerToys/issues/7133) (like Slack).
+
+The dummy key event is currently used in the following places (the linked code snippets contains an example scenario of why it is required):
+- https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L251-L253
+- https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L289-L291
+- https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L382-L383
+- https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L409-L410
+- https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L509-L510
+
+### Suppressing Num Lock in a keyboard hook
+The <kbd>Num Lock</kbd> key state is updated by the OS before it is intercepted by low level hooks. This causes the issue that even if you suppress a <kbd>Num Lock</kbd> key event, <kbd>Num Lock</kbd> will still get toggled. In order to work around this, in the [`hook_proc`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L340-L344) whenever we suppress a <kbd>Num Lock</kbd> key down event, we send an additional <kbd>Num Lock</kbd> key up followed by key down so that the <kbd>Num Lock</kbd> state is reverted to it's previous value before the suppressed event. These are sent with a `KEYBOARDMANAGER_SUPPRESS_FLAG` in the `dwExtraInfo` field, so that we suppress them at the start of the hook (see code [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L811-L825)). Since these events will update the <kbd>Num Lock</kbd> state before the low level hooks, by suppressing them we ensure that these are not sent to any other hooks/applications and hence are only processed by the OS. 
+
+This assumes that KBM is the last hook to be registered (since another hook-based app like AutoHotkey could remap NumLock to some other key which could mess up this logic).
+
+### Modifier-Caps Lock interaction on Japanese IME keyboards
+While using Japanese IME on Windows, shortcuts like <kbd>Shift/Alt/Ctrl</kbd> + <kbd>Caps Lock</kbd> can be used to switch IME options.
+
+![japanese-ime](japanese-ime.png)
+
+These shortcuts are detected before low level hooks, and hence cause issues while remapping <kbd>Caps Lock</kbd> to <kbd>Shift/Alt/Ctrl</kbd> or vice-versa, as there could be an intermediate state where the system detects both the keys as being pressed. This results in a state where the modifier key does not get released since the OS suppresses the key up messages before they reach the low level hooks.
+
+In order to work around this when a key down for the modifier is being processed, we send a key up for the modifier key with the `KEYBOARDMANAGER_SUPPRESS_FLAG` in the `dwExtraInfo` field, so that we suppress them at the start of the hook, and this key event would only be processed by the OS, without getting forwarded to other hooks/apps. The approach is described in more detail at [this comment](https://github.com/microsoft/PowerToys/issues/3397#issuecomment-640136416), as discussed with the AutoHotkey team. The code for the workaround can be found [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L827-L846). Tests for these scenarios have also been added at:
+- [Tests for workaround on single key remaps](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/test/SingleKeyRemappingTests.cpp#L110-L219)
+- [Tests for workaround on shortcut remaps](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/test/OSLevelShortcutRemappingTests.cpp#L1935-L2144)
+
+For example, while [remapping <kbd>Ctrl</kbd> to <kbd>Caps Lock</kbd>](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L59-L63), before sending the <kbd>Caps Lock</kbd> key down message and suppressing <kbd>Ctrl</kbd>, we send a suppressed <kbd>Ctrl</kbd> key up, so that the OS doesn't see <kbd>Ctrl</kbd> and <kbd>Caps Lock</kbd> pressed together at any point. For the [<kbd>Caps Lock</kbd> to <kbd>Ctrl</kbd> scenario](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/KeyboardEventHandlers.cpp#L104-L116), we send a suppressed C<kbd>Ctrl</kbd>trl key up message after sending <kbd>Ctrl</kbd> key down before <kbd>Caps Lock</kbd> suppressed. Similar logic is added for such scenarios in shortcut remapping.
+
+While the above work around fixes most of the cases, there are still some scenarios where the modifier can get stuck, mentioned at this [comment](https://github.com/microsoft/PowerToys/issues/3397#issuecomment-663729278), which is why the issue is still open. This occurs if a modifier is pressed after the remap has been invoked before releasing the remapped key and it is a harder scenario to solve which requires refactoring the single key remap code.
+
+### UIPI Issues (not resolved)
+`SendInput` does not work directly with certain key codes such as Play/Pause Media, Calculator key, etc as it requires UAC privileges to be injected to the OS and accordingly play the active media app or launch the Calculator app. In order to resolve this the correct approach is that the executable which calls `SendInput` needs to have the [UIAccess flag](https://docs.microsoft.com/en-us/windows/win32/winauto/uiauto-securityoverview) set to true, which will also avoid the requirement of KBM having to run as administrator to intercept key events when an elevated window is in focus. The UIAccess flag has many constraints such as it must be a signed executable and must be located in a protected path like Program Files. Since KBM currently runs out of the runner process, it would make more sense to do this work after KBM is moved to a separate executable, and it could be enabled by a separate toggle in settings only if PowerToys is installed in Program Files. [This comment](https://github.com/microsoft/PowerToys/issues/3192#issuecomment-646323661) has more details on this approach and (this)[https://github.com/microsoft/PowerToys/issues/3255] is the tracking issue.
+
+## Other remapping approaches
+Other approaches for remapping which were deprioritized are:
+
+### Registry approach
+This method is used by [SharpKeys](https://github.com/randyrants/sharpkeys) and involves using the [Microsoft Keyboard Scancode mapper registry key](https://github.com/randyrants/sharpkeys) to remap keys based on their scan codes. This has the advantage of being applied in all scenarios and not facing any elevation or UAC issues, however the disadvantages are that for modifying the settings the process must run elevated (as it modifies HKLM registry) and it requires a reboot to get applied. Another issue which is an advantage/disadvantage for users is that the process does not need to be running, so the remaps are applied all the time, including at the password prompt on logging in to the user's Windows account, which could get a user stuck if they orphaned a key in their password. This registry doesn't have any support for remapping shortcuts either, so the hook approach was prioritized over this.
+
+### Driver approach
+Using a driver approach has the benefit of not depending on precedence orders as KBM could always run before low level hooks, and it also has the benefit of differentiating between different keyboards, allowing [multi keyboard-specific remaps](https://github.com/microsoft/PowerToys/issues/1460). The disadvantages are however that any bug or crash could have system level consequences. [Interception](https://github.com/oblitum/Interception) is an open source driver that could be used for implementing this. The approach was deprioritized due to the potential side effects.
+
+## Telemetry
+Keyboard Manager emits the following telemetry events (implemented in [trace.h](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/trace.h) and [trace.cpp](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/trace.cpp)):

+
+## KeyboardManagerState
+[This class](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/KeyboardManagerState.cpp) stores all the data related to remappings and is also used in the sense of a View Model as it used to communicate common data that is shared between the KBM UI and the backend. They are accessed on the UI controls using static class members of `SingleKeyRemapControl` and `ShortcutControl`.
+
+### UI States
+[UI states](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.h#L27-L42) are used to keep track in which step of the UI flow is the user at, such as which Remap window they are on, or if they have one of the Type windows open. This is required because the hook needs to suppress input and update UI in some cases, and in some cases remappings have to be disabled altogether.
+
+### DetectSingleRemapKeyUIBackend and DetectShortcutUIBackend
+[These methods](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L374-L446) are [called on the low level hook](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/dllmain.cpp#L399-L408) in the main keyboard event handler. When the user opens any UI window the UI states are updated and in this case some remappings have to be disabled. On the Remap keys window, all remappings are disabled, while on the Remap shortcuts window, shortcut remappings are disabled. 
+
+In addition to this, if the user has opened the Type window, and the window is in focus, [whenever a key event is received we have to update the set of selected keys in the TextBlock](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L266-L329) in the ContentDialog. These methods also call the `KeyDelay` handlers to check if the input is Esc/Enter and accordingly handle the Accessibility events for the Type window. When the user clicks the Type button, [variables in the KeyboardManagerState store the corresponding TextBlocks](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/SingleKeyRemapControl.cpp#L375-L376) which appear in the ContentDialog, so that these UI controls can be updated from the hook on the dispatcher thread.
+
+### HandleKeyDelayEvent
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L482-L498) checks if the UI is in the foreground, and if so runs the key delay handlers that have been registered.
+
+### Saving remappings to file
+The [`SaveConfigToFile`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L500-L607) method is called on clicking the OK button on the EditKeyboardWindow or EditShortcutsWindow. Since PowerToys Settings also reads the config JSON file, [a named mutex is used](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L582-L600) before accessing the file, with a 1 second timeout. If the mutex is obtained the settings are written to the default.json file.
+
+### Concurrent Access to remap tables
+To prevent the UI thread and low level hook thread from concurrently accessing the remap tables we use an [`atomic bool` variable](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.h#L91-L92), which is set to `true` while the tables are getting updated. When this is `true` the hook will skip all remappings. Use of mutexes in the hook were removed to prevent re-entrant mutex bugs.
+
+## KeyDelay
+[This class](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/KeyDelay.cpp) implements a queue based approach for processing key events and based on the time difference between key down and key up events [executes separate methods for `ShortPress`, `LongPress` or `LongPressReleased`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyDelay.h#L69-L72). The class is used for the hold Enter/Esc functionality required for making the Type window accessible and prevent keyboard traps (see [this](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/SingleKeyRemapControl.cpp#L273-L292) for an example of it's usage). The `KeyEvents` are added to the queue from the hook thread of KBM, and a separate [`DelayThread`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyDelay.cpp#L142-L166) is used to process the key events by checking the `time` member in the key event. The thresholds for short vs long press and hold wait timeouts are `static` constants, but if the module is extended for other purposes these could be made into arguments.
+
+**Note:** [Deletion of the `KeyDelay`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyDelay.cpp#L4-L12) object should never be called from the `DelayThread` i.e. from within one of the 3 handlers, as it can re-enter the mutex and would lead to a deadlock. This can be avoided by either deleting it on a separate thread or as done in the KBM UI, on the dispatcher thread. See [this PR](https://github.com/microsoft/PowerToys/pull/6959#issue-496583547) for more details on this issue.
+
+## Shortcut and RemapShortcut classes
+The [`Shortcut` class](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/Shortcut.h) is a data structure for storing key combinations which are valid shortcuts and it contains several methods which are used for shortcut specific operations. [`RemapShortcut`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/RemapShortcut.h) consists of a shortcut/key union (`std::variant`), along with other boolean flags which are required on the hook side for storing any relevant keyboard states mid-execution.
+
+### IsKeyboardStateClearExceptShortcut
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Shortcut.cpp#L665-L813) is used by the `HandleShortcutRemapEvent` to check if any other keys on the keyboard have been pressed apart from the keys in the shortcut. This is required because shortcut to shortcut remaps should not be applied if the shortcut is pressed with other keys. The method iterates over all the possible key codes, except any keys that are considered reserved, unassigned, OEM-specific or undefined, as well as mouse buttons (see list [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Shortcut.cpp#L628-L663)).
+
+### CheckModifiersKeyboardState
+[This method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Shortcut.cpp#L517-L614) uses `GetVirtualKeyState` (internally calls `GetAsyncKeyState` in production code), to check if all the modifiers of the current shortcut are being pressed. Since Win doesn't have a non-L/R key code we check this by checking both LWIN and RWIN.
+
+### Tests
+Tests for some methods in the `Shortcut` class can be found [here](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/ShortcutTests.cpp).
+
+## Helpers
+[This namespace](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/common/Helpers.cpp) has any methods which are used across either UI or the backend which aren't specific to either. Some of these methods have tests [here](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/SetKeyEventTests.cpp).
+
+### Foreground App Detection
+[`GetCurrentApplication`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L226-L268) is used for detecting the foreground process for App-specific shortcuts. The logic is very similar to that used for FZ's app exception feature, involving `GetForegroundWindow` and `get_process_path`. The one additional case which has been added is for full-screen UWP apps, where the above method fails and returns `ApplicationFrameHost.exe`. The [`GetFullscreenUWPWindowHandle`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/Helpers.cpp#L210-L224) uses `GetGUIThreadInfo` API to find the window linked to the GUI thread. This logic is based on [this stackoverflow answer](https://stackoverflow.com/questions/39702704/connecting-uwp-apps-hosted-by-applicationframehost-to-their-real-processes/55353165#55353165).
+
+**Note:** The [`GetForegroundProcess` method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/dll/Input.cpp#L17-L21) performs string allocation in a weird way because of exceptions that were occurring while running tests as a result of memory being allocated or deallocated across dll boundaries. Here's the comment from the PR where this was added
+> To make app-specific logic test-able, a GetForegroundProcess was added to the input interface which internally calls GetCurrentApplication. This allows us to mock this method in the test project by just setting some process name as the foreground process for that function. When I set this to just return the string name, it would goes runtime errors on the test project in debug_heap with `__acrt_first_block == header`. Based on [this stackoverflow answer](https://stackoverflow.com/a/35311928), this would happen if allocation happens in one dll's code space and deallocation happens in another. One way to avoid this is to change both the projects to MD (multi threaded dll) instead of MT(multi threaded), however that results in many compile-time errors since all the PT projects are configured as MT. To solve this, the GetForegroundProcess was rewritten such that its argument is the output variable, and we allocate memory for that string within the AppSpecificHandler method rather than in that function.

+
+## C++ XAML Islands
+The KBM UI is implemented as a C++ XAML Island, but all the controls are implemented in code behind rather than .xaml and .xaml.cs files. This was done as per a XAML Island Code sample and it didn't require a separate UWP project, which could be limited in terms of using hooks. There is a [tech debt item](https://github.com/microsoft/PowerToys/issues/2027) for moving this to XAML. The reason it wasn't implemented in the C# Settings was because it required communication with the low level hook thread, which could be too slow if IPC is used, since the UI needs to update on every key event.
+
+**Note:** For functions which take a XAML component as argument, pass it by value and not by reference. This is because `winrt` WinUI classes store their own internal references, so they are supposed to be passed by value (and internally ref counts are incremented). Passing by reference can lead to weird behavior where the object is `null`.
+
+The windows are [created as C++ windows](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L128-L140) and the window sizes are set to default by [scaling them as per DPI](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L120-L126) using the `DPIAware::Convert` API from common lib. Since the UI is launched on a new thread, the window may not be in the foreground, so [we call `SetForegroundWindow`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L146-L150).
+
+`DesktopWindowXamlSource` has to be declared and [it is initialized](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L159-L162) using the [`XamlBridge`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/ui/XamlBridge.cpp), and [a second window handle](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L161-L162) is generated for the internal Xaml Island window. Most of the code was based on the [Xaml Island Sample](https://github.com/microsoft/Xaml-Islands-Samples/blob/master/Samples/Win32/SampleCppApp/XamlBridge.cpp). The `XamlBridge` class contains code which handles initializing the Xaml Island containers as well as handling special messages like keyboard navigation, and focus between islands and between the C++ window and the island. It also has methods for clearing the xaml islands and closing the window.
+
+Once the UI controls are created, the parent container is set as the content for the `DesktopWindowXamlSource` and the `XamlBridge.MessageLoop` is executed. Messages are processed by the C++ window handler like [`EditKeyboardWindowProc`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L364-L404). The general structure we use for this is, for any `WM_PAINT` or `WM_SIZE` message we resize the Xaml Island window. For `WM_GETMINMAXINFO` we set minimum widths so that the window cannot be resized beyond a minimum height and width. This is done to prevent the WinUI elements from overlapping and getting cropped. If it is neither of these cases we send the message to the [`XamlBridge.MessageHandler`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/XamlBridge.cpp#L291-L301) which handles Destroy, Activation and Focus. If `WM_NCDESTROY` is received when the `XamlBridge` is `nullptr`, the window thread is terminated.
+
+**Note:** `ContentDialog` in Xaml Islands requires manually settings a `XamlRoot`. This can generally be done by passing the XamlRoot from a component in the main window, such as the button used to open the dialog ([`sender.as<Button>().XamlRoot()`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/ShortcutControl.cpp#L31-L32)). [These docs]((https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.contentdialog#contentdialog-in-appwindow-or-xaml-islands)) have more details about this.
+
+### Debugging exceptions in XAML Islands
+Sometimes if an exception occurs in XAML Islands, the stack trace may not always point to the correct code causing the exception and instead it will point to the Xaml Island message loop. In these cases the output window in VS will generally show the correct exception.
+
+### Build times
+C++ Xaml Islands generally take several minutes to build because the `pch` which contains the WinUI headers takes longer to build and compiles to a file of several GBs. To minimize the build times, multi-processor compilation within the projects have been enabled (files are distributed for compilation to the processors), and references to the Xaml headers have been removed from the .h headers files as much as possible. Since several classes of ours had class members with UI controls like `StackPanel` (which requires definitions of the classes in order to compile), we worked around this by declaring them as `IInspectable` (the equivalent of an object pointer in winrt), and initializing them to the actual control like `StackPanel` in the constructor and accessing all their member functions by inline typecasting (for `IInspectable x;` we do `x = StackPanel();` and `x.as<StackPanel>().MemberFunction()`). Check [this](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/ShortcutControl.cpp#L19-L25) for this type of usage in `ShortcutControl`.
+
+### Setting custom backgrounds for Xaml Controls using brushes
+To access the brushes available on C# Xaml, it has to be done with the `Resources.Lookup` syntax:
+`primaryButton.Background(Windows::UI::Xaml::Application::Current().Resources().Lookup(box_value(L"SystemControlBackgroundBaseMediumLowBrush")).as<Windows::UI::Xaml::Media::SolidColorBrush>());`
+
+## UI Structure
+The KBM UI consists of a [`Grid` with several columns](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L200-L218). Rows are added dynamically when [the add button is pressed](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L305-L309). [A vector of vector of unique pointers to `SingleKeyRemapControl`/`ShortcutControl`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L248-L249) is created so that references to the UI components and their data are not lost until the window is closed. [`SingleKeyRemapControl`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/ui/SingleKeyRemapControl.cpp) is the UI class for each row of the Remap keys table, and [`ShortcutControl`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/ui/ShortcutControl.cpp) is the UI class for each row of the Remap shortcuts table. [`KeyDropDownControl`](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp) is used for handling the ComboBox operations. Each of these two classes [have vectors of unique pointers to the `KeyDropDownControl` objects](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/ShortcutControl.h#L44-L45) so that references to the objects are active until the control is deleted.
+
+When the UI windows are activated the `KeyboardManagerState` object [sets the `UIState` variable](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L251-L252) which is used for distinguishing if the UI is up from the keyboard hook thread. The [states are also updated](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/SingleKeyRemapControl.cpp#L53) on opening and closing the Type window.
+
+Clicking the Type Button [opens a content dialog](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/SingleKeyRemapControl.cpp#L206-L380) which registers key delays using the [`KeyDelay` class](keyboardmanagercommon.md#KeyDelay) for Enter and Esc keys and sets the UI states such that when a key event occurs the TextBlocks on the ContentDialog are updated accordingly. On accepting the dialog the selected keys are copied into the ComboBoxes from the TextBlocks, and on closing the window the key delays are unregistered and UI states are reset.
+
+Since ComboBoxes are added dynamically, handlers have been added which [update the accessible names for these controls](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L69-L74), which get executed whenever a drop down is added or removed.
+
+When the `EditKeyboardWindow`/`EditShortcutsWindow` is created, [we iterate through the remappings](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L254-L262) stored in `KeyboardManagerState` and add rows to the UI Grid. For both the windows we have `static` buffers [`singleKeyRemapBuffer`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/SingleKeyRemapControl.h#L39-L40) and [`shortcutRemapBuffer`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/ShortcutControl.h#L42-L43) which store the corresponding key/shortcuts as per the selections in the UI if they are valid with no warnings.
+
+## EditKeyboardWindow/EditShortcutsWindow 
+
+### OK and Cancel button
+[On pressing the OK button](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditKeyboardWindow.cpp#L66-L89) in `EditKeyboardWindow`, first the [`CheckIfRemappingsAreValid` method](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/LoadingAndSavingRemappingHelper.cpp#L10-L44) is executed which performs basic validity checks on the current remappings in the remap buffer (`static SingleKeyRemapControl::singleKeyRemapBuffer`), such as if there are no NULL columns and none of the source keys are repeated. All other validity checks are assumed to happen while the user adds the remapping. If this is found to be invalid a ContentDialog is displayed which shows that some remappings are invalid and if the user proceeds only the valid ones will be applied. If it is valid [`GetOrphanedKeys`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/LoadingAndSavingRemappingHelper.cpp#L46-L75) is executed which checks if any keys are orphaned (i.e. the key has been remapped and no other key has been remapped to it, so there is no way to send that key code), and a dialog is shown for notifying the user with a list of orphaned keys. After this the settings are [applied by adding it to the `KeyboardManagerState.singleKeyReMap` member](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/LoadingAndSavingRemappingHelper.cpp#L102-L164) and they are saved to the JSON file. `EditShortcutsWindow` differs slightly from this, as there is no orphaned keys check, and [on pressing OK](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/EditShortcutsWindow.cpp#L32-L47) both the global and app-specific shortcuts are validated and [updated](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/LoadingAndSavingRemappingHelper.cpp#L166-L223).
+
+The code used for updating the remapping tables in `KeyboardManagerState` can be found [here](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L104-L183). For shortcut remaps, the `sortedKeys` vectors are updated and re-sorted whenever an element is added to them (like [this](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/common/KeyboardManagerState.cpp#L135-L136)).
+
+On pressing OK (after confirmation dialogs) or Cancel, the window is closed and UI states are reset.
+
+### Delete button
+Since there is no single method to delete the elements in a row for a Grid, [the logic](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/SingleKeyRemapControl.cpp#L143-L188) we use involves decrementing the rowIndex for all the UI controls that appearing after the row to be deleted, and removing each of the items of the row from the Grid, followed by deleting that row definition. We also update the accessible names for all the rows since the indexing has changed. After this the corresponding row in the remap buffer is also deleted, and `SingleKeyRemapControl`/`ShortcutControl` objects are deleted from the vector.
+
+### Handling common modifiers in EditKeyboardWindow
+In the SingleKeyRemap table for a remapping of the form Ctrl->X, where Ctrl is the common version and not L/R, we can't store it directly as Ctrl->X because when the hook receives the key event it only gets LCtrl or RCtrl specifically and not `VK_CONTROL`. To simplify the backend code, when [single key remappings are applied](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/LoadingAndSavingRemappingHelper.cpp#L116-L143), any remapping of the form Ctrl->X is split into Ctrl(L)->X and Ctrl(R)->X (i.e. both L and R versions are remapped to the same target), and when remappings are loaded in EditKeyboardWindow, we [pre-process the remap table](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/LoadingAndSavingRemappingHelper.cpp#L77-L100) such that if the L and R versions of a modifier are remapped to the same key/shortcut we combine them. This also results in the behavior where a user adds LCtrl->X and RCtrl->X and after closing and re-opening KBM UI it appears combined as Ctrl->X.
+
+## SingleKeyRemapControl
+The left drop down column uses a single ComboBox and the Type button is linked to `createDetectKeyWindow`, whereas the right column is linked to `createDetectShortcutWindow` as the column can accept a key or a shortcut (required to support key to key and key to shortcut). The `KeyDropDownControl` for the left column in the window uses a smaller key list, without `None`.
+
+## ShortcutControl
+Both the columns in are linked to `createDetectShortcutWindow`, however the drop down selection handlers differ in their logic as the left column only allows shortcuts, and the drop downs do not contain the `Disable` key, whereas the right column allows you to select both shortcuts and keys (to support shortcut to shortcut and shortcut to key), and it allows selection of `Disable`.
+
+For the app-specific shortcut target app text-box, we had to validate that the shortcut row is still valid when the target app is changed (for example, <kbd>Ctrl+A</kbd> is remapped for Chrome, and another remapping for <kbd>Ctrl+A</kbd> was remapped to Edge, but the target was changed to Chrome.). For this we didn't use the TextChanged handler as every time a letter is typed it would get executed. Instead we used the [`LostFocus` handler](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/ShortcutControl.cpp#L108-L167) which gets executed whenever you focus into the box (by clicking or tabbing) and then tabbing or clicking out. In the method we perform the same shortcut buffer validation used for selections in the drop down menus and update the buffers accordingly.
+
+## KeyDropDownControl
+Each ComboBox has a linked flyout, which is used to show warnings to the users whenever a user selects an invalid key from the drop down. When the warning is displayed the ComboBox is also reset to -1, i.e. no selection.
+
+For selection handlers on the ComboBoxes we couldn't use just the SelectionChanged handler directly as it gets executed even on searching for elements in the drop down. Instead we used DropDownClosed (when a user opens the drop down and searches and selects something) and SelectionChanged when the drop down is not open (for setting selections programmatically or selection made by searching with tab focus on the drop down without opening it). This was required because if we execute the selection handlers while users are searching, it could cause false positive flyout warnings if the search causes an invalid value to be selected, and flyouts cause the drop down to close leading to bad UI experience.
+
+### Localized key names
+For getting localized key names and symbols for each virtual key code, whenever the key lists are accessed, i.e. [whenever the drop down is opened](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L56-L60) or when `GetKeyName` is called in the Type window, the current `KeyboardLayout` is retrieved to ensure that the displayed key names are always updated. Since the `WM_INPUTLANGCHANGED` event was having some issues with XAML islands we weren't able to use this to update the keyboard layout. In addition to this we do not refresh the UI, so the key lists get updated only on opening/interacting with them.

+### Single Key ComboBox Selection Handler
+On making a selection in the drop down, [the selection handler](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L91-L130) validates the input with the buffer from the other column and other rows. Error messages are shown using flyouts if the selection is not considered valid and the drop down and buffer for that entry are reset to empty selection. The errors that can occur on the single key ComboBox are:
+- Remap to same key (A->A)
+- Same key previously remapped (A->B and A->C)
+- Conflicting modifier previously remapped (Ctrl->A and Ctrl(left)->B, since Ctrl also includes Ctrl(left))
+If the selection is found to be valid, the `singleKeyRemapBuffer` is updated accordingly.
+For handling `Shortcut` and key in the remap buffer for the right column, we use `std::variant`, which allows us to store either of the two types and check which one of them is present in the buffer by using the `index` method.
+[`ValidateAndUpdateKeyBufferElement`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/BufferValidationHelpers.cpp#L8-L66) does not reference any UI components and instead takes all the relevant data as arguments. This method [has tests](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/BufferValidationTests.cpp) which covers all the cases that could arise from making selections on the UI.
+
+### Shortcut ComboBox Selection Handler
+On making a selection in the drop down, [the selection handler](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L215-L295) validates the input with the buffer from the other column and other rows. Error messages are shown using flyouts if the selection is not considered valid and the drop down and buffer for that entry are reset to empty selection.
+This differs from the Single Key ComboBox handler in the sense that after validating the current selection we may perform [a set of actions](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L160-L204) such as:
+- Adding a drop down (if a modifier is selected)
+- Removing a drop down (if None is selected)
+- Clearing terminal empty drop downs (if an action key is selected in a non-last drop down and the remaining ones are empty)
+
+After performing the corresponding action, if any, we check if the drop down resulted in an error, in which case we do [a second level of validation](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L224-L229) on all the drop downs in that list of drop downs. This is done because there can be cases where an error in one drop down results us setting it to empty, and the remaining selection is also invalid. For example, you have Ctrl+A -> Ctrl+Shift+A, and you change Shift to Ctrl. This would show a warning for having two Ctrls in the shortcut being invalid, after which setting that to empty would result in Ctrl+A->Ctrl+Empty+A, which is a case of remapping a shortcut to itself.
+
+Once this second level of validation is done, we proceed with [updating the buffer](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L231-L251). Depending on the number of drop downs with valid values, this could be either a key or a shortcut (for the right columns). We also [set the buffer value for the target app](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L252-L267) while doing this.
+
+Unlike the Single Key handler, there is a different set of errors that can occur here which are related to making a selection that is considered as a valid shortcut. The `isHybridControl` argument is used to distinguish between the differing behaviors for the two types of columns (shortcut only or shortcut/key column). The errors that can occur for this handler are:
+- Shortcut must start with modifier (selecting A on the first drop for the left column is invalid)
+- Shortcut can't have a repeated modifier (Ctrl+Ctrl(left)+A is not a shortcut)
+- Shortcut can only have upto 2 modifiers (Ctrl+Shift+Alt is not supported as we have enforced a 3 key constraint (**not a backend limitation, there is [an issue](https://github.com/microsoft/PowerToys/issues/3936) requesting to remove this**))
+- Shortcut must contain an action key (Ctrl+A and change A to None, only for left column)
+- Shortcut must have at least two keys (Ctrl+A and change Ctrl to None, only for left column)
+- Disable can't be a modifier or action key (Ctrl+Disable is invalid)
+- Shortcut can't have more than one action key (Ctrl+Shift+A, change Shift to B)
+- Remap to same shortcut(Ctrl+A->Ctrl+A)
+- Same shortcut previously remapped for same target app (Ctrl+A->B and Ctrl+A->C)
+- Conflicting shortcut previously remapped for same target app (Ctrl+A->B and Ctrl(left)+A->C, since Ctrl also includes Ctrl(left))
+- Illegal shortcut remaps like Win+L or Ctrl+Alt+Del (since these cannot be remapped using LL hooks)
+
+[`ValidateShortcutBufferElement`](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/BufferValidationHelpers.cpp#L68-L304) does not reference any UI components and instead takes all the relevant data as arguments. This method [has tests](https://github.com/microsoft/PowerToys/blob/master/src/modules/keyboardmanager/test/BufferValidationTests.cpp) which covers all the cases that could arise from making selections on the UI.
+
+**Note:** After updating the buffer we have [code to handle a special case](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L269-L279), which was required to prevent scenarios where a drop down can get deleted but the corresponding `KeyDropDownControl` object isn't deleted. The code checks if the drop down is still linked to the parent and accordingly deletes the `KeyDropDownControl` object from the vector.
+
+**IgnoreKeyToShortcutWarning special case:** [An additional](https://github.com/microsoft/PowerToys/blob/b80578b1b9a4b24c9945bddac33c771204280107/src/modules/keyboardmanager/ui/KeyDropDownControl.cpp#L177-L181) check was added to ignore the Map to Same key error when an existing remapping is loaded. This was because a remapping like Ctrl->Ctrl+A has an intermediate step of Ctrl->Ctrl, which could lead to an error of invalid input, even though Ctrl+A is valid. The only way to actually add this is from the Type button or by adding them in a different order (like typing Shift+A and then changing Shift to Ctrl). Since the intermediate check could fail, this was causing the app to crash since the Xaml Island wouldn't be completely loaded at that point and the Flyout can't be displayed. [This](https://github.com/microsoft/PowerToys/issues/6695) is the linked issue which describes the repro scenario.

+# Architecture 
+
+## Overview
+`PowerToys Run` is a plugin-based .net core desktop application. It is written in WPF using `Model-View-ViewModel (MVVM)` structural design pattern. This article provides an overview of `PowerToys Run` architecture and introduces major components in the data flow.
+
+Note : We refer to base application without plugins as `PowerLauncher`, which is same as the name of startup WPF project. 
+
+## UI
+PowerToys Run UI is written in the WPF framework. The UI code is present in the Powerlauncher project and is spanned across three high-level components: [`MainWindow.xaml`](/src/modules/launcher/PowerLauncher/MainWindow.xaml), [`LauncherControl.xaml`](/src/modules/launcher/PowerLauncher/LauncherControl.xaml) and [`ResultList.xaml`](/src/modules/launcher/PowerLauncher/LauncherControl.xaml). These components are discussed below. 
+
+![Image of PowerToys Run UI](/doc/images/launcher/pt_run_ui.png)
+**Fig 1: PowerToys Run UI architecture**
+
+1. **[`MainWindow.xaml`](/src/modules/launcher/PowerLauncher/MainWindow.xaml)**: This is the outermost-level UI control. It is composed of lower-level UI components such as [`LauncherControl.xaml`](/src/modules/launcher/PowerLauncher/LauncherControl.xaml) and [`ResultList.xaml`](/src/modules/launcher/PowerLauncher/LauncherControl.xaml). The corresponding code-behind file implements all the UI related functionalities such as autosuggest, key-bindings, toggling visibility of WPF window and animations.
+2. **[`LauncherControl.xaml`](/src/modules/launcher/PowerLauncher/LauncherControl.xaml)**: This control implements the UI component for editing query text.(marked in red in Fig 1) It consists of two overlapping WPF controls, `TextBox` and `TextBlock`. The outer `TextBox` is used for editing query whereas the inner `TextBlock` is used to display autosuggest text.
+3. **[`ResultList.xaml`](/src/modules/launcher/PowerLauncher/LauncherControl.xaml)**: This control implements the UI component for displaying results (marked in green in Fig 1). It consists of a `ListView` WPF control with a custom `ItemTemplate` to display application logo, name, tooltip text, and context menu.
+
+## Data flow
+The backend code is written using the `Model-View-ViewModel (MVVM)` structural design pattern. Plugins act as `Model` in this project. A detailed overview of the project's structure is given [here](/doc/devdocs/modules/launcher/project_structure.md).
+
+#### Flow of data between UI(view) and ViewModels
+Data flow between View and ViewModel follows typical `MVVM` scheme. Properties in viewModels are bound to WPF controls and when these properties are updated, `INotifyPropertyChanged` handler is invoked, which in turn updates UI. The diagram below provides a rough sketch of the components involved.
+![Flow of data between UI(view) and ViewModels](/doc/images/launcher/ui_vm_interaction.PNG)
+**Fig 2: Flow of data between UI and ViewModels.**
+
+#### Flow of data between ViewModels and Plugins(Model)
+`PowerLauncher` interact with plugins using [`IPlugin`](/src/modules/launcher/Wox.Plugin/IPlugin.cs) and `IDelayedExecutionPlugin` interface. [`IPlugin`](/src/modules/launcher/Wox.Plugin/IPlugin.cs) is used for initialization and making queries which are fast (typically return results in less than 100ms).[`IDelayedExecutionPlugin`](/src/modules/launcher/Wox.Plugin/IDelayedExecutionPlugin.cs) is used for long-running queries and is implemented only when required. For example, [`IDelayedExecutionPlugin`](/src/modules/launcher/Wox.Plugin/IDelayedExecutionPlugin.cs) is implemented by indexer plugin for searching files with names of form \*abc\*.
+```
+    public interface IPlugin
+    {
+        // Query plugin
+        List<Result> Query(Query query);
+
+        // Initialize plugin
+        void Init(PluginInitContext context);
+    }
+
+    public interface IDelayedExecutionPlugin : IFeatures
+    {
+        // Query plugin
+        List<Result> Query(Query query, bool delayedExecution);
+    }
+```
+![Flow of data between UI(view) and ViewModels](/doc/images/launcher/vm_plugin_interaction.PNG)
+**Fig 3: Flow of data between ViewModels and Plugins.**
+
+#### Requesting services from powerlauncher
+Plugins could use the [`IPublicAPI`](/src/modules/launcher/Wox.Plugin/IPublicAPI.cs) interface to request services such as getting the current theme (for deciding logo background), displaying messages to the user, and toggling the visibility of PowerLauncher.

+# Debugging
+`PowerToys Run` is a single exe file associated with `launcher.exe` process and debugger should be attached to this process. There are two approaches to debug `PowerToys Run`. Both these approaches differ in the compile-time and the range of functionalities that could be debugged. These methods are discussed in detail in the following sections.
+
+
+## Debugging Prerequisite
+Setup development environment for PowerToys by following instruction [here.](https://github.com/microsoft/PowerToys/tree/master/doc/devdocs#prerequisites-for-compiling-powertoys)
+
+## Direct debugging
+This approach is used to test UI, plugins, and core `PowerToys Run` functionality. This **cannot** be used to test `PowerToys Run` settings. The approach is significantly faster compared to `Debugging with runner`, as it requires compiling projects relevant to `PowerToys Run`. Please follow the steps below for direct debugging.
+1. Right-click on `modules->launcher->PowerLauncher` and select `Set as startup Project`. 
+2. Press `F5` to start debugging.
+
+## Debugging with runner
+This approach can be used to test UI, plugins, core `PowerToys Run` functionality and `PowerToys Run` settings. This approach **cannot** be used to debug functions that execute on starting `launcher.exe` process. This requires building runner along with all the other modules on first compile, making it slower than `Direct debugging` approach. The subsequent compilations should be fast.
+1. Right-click on `runner` and select `Set as startup Project`. 
+2. Press `F5` to start debugging.
+3. Attach debugger to `launcher.exe` process. 
+    1. Go to `Debug->Attach to process..`
+    2. Filter and select `launcher.exe` process. 
+    3. Click on `Attach`.

+
+![Image of Indexer plugin](/doc/images/launcher/plugins/indexer.png)
+
+### [Drive Detection](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/DriveDetection)
+- There are two indexing modes in Windows:
+    1. **Classic mode**: Only the desktop and certain customizable locations in the system are indexed. All the systems have the classic mode enabled by default.
+    2. **Enhanced Mode**: This mode indexes the entire PC when enabled. The user can exclude certain locations from being indexed in this mode from the Windows Search settings options.
+- A drive detection warning is displayed to the users when only the custom mode is enabled on the system informing the user that not all the locations on their PC are indexed as this could lead to some results not showing up.
+- The [`IndexerDriveDetection.cs`](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/DriveDetection/IndexerDriveDetection.cs) file gets the status of the drive detection checkbox in the settings UI and depending on whether the enhanced mode is enabled or disabled, displays the warning.
+- To determine whether the `EnhancedMode` is enabled or not, we check the local machine registry entry for `EnableFindMyFiles`. If it is set to 1, the enhanced mode is enabled.
+
+### [`OleDBSearch`](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/SearchHelper/OleDBSearch.cs)
+- The `Query` function within the [`OleDBSearch.cs`](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/SearchHelper/OleDBSearch.cs) class takes in the query and the connection string to the SystemIndex catalog as arguments and returns a list of results.
+- It first opens a [connection][OLEDBConnection] to the Windows Indexer database, creates an [OleDB command][OLEDBCommand] and executes the command to get a list of results.
+
+### [`WindowsSearchAPI`](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/SearchHelper/WindowsSearchAPI.cs)
+- The [`WindowsSearchAPI`](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/SearchHelper/WindowsSearchAPI.cs) class leverages the [`OleDBSearch.cs`](src/modules/launcher/Plugins/Microsoft.Plugin.Indexer/SearchHelper/OleDBSearch.cs) class to execute the query.
+- It initializes the `QueryHelper` in the `InitQueryHelper()` function by creating a catalog manager to the SystemIndex catalog.
+- The metadata is initialized within the query helper, such as the number of results to retrieve, the type of information to retrieve for each file (currently we retrieve the item URL, the file name and the file attributes).
+- The query helper matches results using the name of the file only and they are sorted by the last modified date, ensuring that the recently modified files are ranked higher.
+- The File attributes are utilized to filter out hidden files from being displayed. 
+
+### Additional Information
+- There are two major types of queries generated by the indexer plugin:
+    1. Full Text predicates - eg: [CONTAINS][Contains]
+    2. Non-Full Text predicates - eg: [LIKE][Like]
+- The Full text predicates are much faster than non-full text predicates as they are based on finding matches rather than comparing the query with each item in the indexer database. Hence, queries which have the `CONTAINS` keyword are much faster than those which contain the `LIKE` keyword.
+- To prevent the indexer query from taking a long time and blocking the UI thread, there are two types of indexer queries which are executed. A simplified query and a full query, without and with the `LIKE` keyword respectively.
+- The result list is updated with the results of the full query once they are obtained.
+
+### Score
+Each of the indexer plugin results has a score set to 0 so they are present at the bottom of the list.

+# Structural Overview
+The following basic functions are common to each of the plugins. They perform some rudimentary operations such as initialization of the plugin, executing the query that has been entered, loading context menu icons, updating settings when configurations are altered in the settings UI, and updating the theme of the icons when the theme changed event is triggered.
+
+## IPlugin Interface
+Each plugin implements the `IPlugin` interface which comprises of the `Init()` and `Query()` functions.
+
+### `Init`
+- The `Init()` function initializes the context, storage and settings of each plugin. This is equivalent to a constructor and is the first function to be called in the `Main.cs` file for each plugin.
+
+### `Query`
+- For every query that the user enters into PT Run, the `PluginManager.cs` executes the `Query()` function in the `Main.cs` file corresponding to each Plugin.
+
+### Context Menu Icons
+- The `ContextMenus` are loaded for each result based on the type of the result.
+- The various types of `ContextMenu` functionalities are:
+    - Open containing folder
+    - Run as Administrator
+    - Open in console
+    - Copy path
+
+### UpdateSettings
+- This function updates the settings of each plugin based on the changes made by the user in the settings UI.
+- Eg: To disable drive detection in the indexer plugin, when the user checks or unchecks the drive detection check box, the `UpdateSettings()` function dispatches the changes in the check box to the plugin.
+
+### ThemeChanged
+- This function is invoked when there is a change in the theme of PT Run.
+- It is used to update the `IconPath` for each plugin based on the theme.
+
+### Save
+- This function saves the configurations of each plugin so that they can be loaded the next time.
+
+### Score
+- The user query is executed against each of the plugins and the result list view is updated with results from each of the plugins.
+- The ordering of the results is based on the `Score` of each Result.
+- Each plugin assigns a score to a result based on it's relevance. The results with higher scores are displayed higher in the list view and vice versa.

+# Program Plugin
+The program plugin as the name suggests is used to search for programs installed on the system.
+
+![Image of Program plugin](/doc/images/launcher/plugins/program.png)
+
+There are broadly two different categories of applications:
+
+1. Packaged applications
+2. Win32 applications
+
+### [UWP](src/modules/launcher/Plugins/Microsoft.Plugin.Program/Programs/UWP.cs)
+- The logic for indexing Packaged applications is present within the [`UWP.cs`](src/modules/launcher/Plugins/Microsoft.Plugin.Program/Programs/UWP.cs) file.
+- There can be multiple applications present within a package. The [`UWPApplication.cs`](src/modules/launcher/Plugins/Microsoft.Plugin.Program/Programs/UWPApplication.cs) file encapsulates the properties of a packaged application.
+- To index packaged applications, the `PackageManager` retrieves all the packages for the current user and indexes all the applications.
+- To retrieve the app icon for packaged applications, the assets path is retrieved from the `Application Manifest` file. There are multiple icons corresponding to each scale, target size and theme. The best icon is chosen given the theme of powerToys Run.
+
+### [Win32Program](src/modules/launcher/Plugins/Microsoft.Plugin.Program/Programs/Win32Program.cs)
+- Win32 programs in the following locations are indexed by PT Run-
+    1. Desktop
+    2. Public Desktop (Applications present on the desktop of all the users)
+    3. Registry (Some programs)
+    4. Start Menu
+    5. Common start menu (Applications which are common to all users)
+    8. Locations pointed to by the PATH environment variable.
+- To prevent applications and shortcuts present in multiple locations from showing up as duplicate results, we consider apps with the same name, executable name and full path to be the same.
+- The subtitle of the application result is set based on it's application type. It could be one of the following:
+    1. Lnk Shortcuts
+    2. Appref files
+    3. Internet shortcut - steam and epic games
+    4. PWAs
+    5. Run commands - these are indexed by the PATH environment variable
+
+### Score
+- The score for each application result is based on the how many letters are matched, how close the matched letters are to the actual word and the index of the matched characters.
+- There is a threshold score to decide the apps which are to be displayed and applications which have a lower score are not displayed by PT Run.
+
+### Update Program List in Runtime
+- Packaged and Win32 app helpers exist to reflect changes in the list of indexed apps when applications are installed on the system while PT Run is executing.
+- Packaged applications trigger events when the package is being installed and uninstalled. PT Run listens to those events to index applications which are newly installed or to delete an app which no longer exists from the database.
+- No such events exist for Win32 applications. We therefore use FileSystem Watchers to monitor the locations that we index for newly created, deleted or renamed application files and update the indexed Win32 catalog accordingly.
+
+### Additional Notes
+- Arguments can be provided to the program plugin by entering them after `--` (a double dash).

+### Functionality
+- The Shell command expands environment variables, so `>%appdata%` works as expected.
+- On inheriting the Shell plugin from Wox, there are three different ways of executing a command, using the command prompt, powershell or the run prompt. To uphold the name of PT Run, the Shell plugin always executes commands as the Run prompt would.
+- The Shell plugin has a concept of history where the previously executed commands show up in the drop down list along with the number of times they have been executed.
+- The Run prompt has the folder plugin function where we can navigate to different locations and entering the path to a directory displays all the sub-directories. To prevent reimplementing this logic, the shell plugin references the folder plugin to implement this functionality.

+# Project Structure
+## Overview
+`PowerToys Run` is divided across several projects to keep a logical separation between plugins and core functionality. The following sections provide a brief overview of each project.
+
+![Image of project dependency](/doc/images/launcher/launcher_dependency.PNG)
+Fig 1. Project along with their dependencies in `PowerToys Run` ecosystem.
+
+## Project Description
+#### [`PowerLauncher`](/src/modules/launcher/PowerLauncher)
+This is the startup project for the `PowerToys Run.` It is a WPF desktop application and follows the `Model-View-ViewModel (MVVM)` design pattern. Plugins play the role of `Model` and provide data to `ViewModel.`
+
+#### [`PowerLauncher.Telemetry`](/src/modules/launcher/PowerLauncher.Telemetry)
+[`PowerLauncher.Telemetry`](/src/modules/launcher/PowerLauncher.Telemetry) is a .net core project that contains telemetry events generated by `PowerLauncher.` These events have been discussed in detail [here](/doc/devdocs/modules/launcher/telemetry.md). 
+
+#### [`Wox.Core`](/src/modules/launcher/Wox.Core)
+[`Wox.Core`](/src/modules/launcher/Wox.Core) is a .net core project that contains helper classes required by the `PowerLauncher` project. Two major functionalities encapsulated in this project are [`PluginManager`](/src/modules/launcher/Wox.Core/Plugin/PluginManager.cs) and [`Query Builder.`](/src/modules/launcher/Wox.Core/Plugin/QueryBuilder.cs) [`PluginManager`](/src/modules/launcher/Wox.Core/Plugin/PluginManager.cs) provides an interface for managing C# plugins. [`Query Builder.`](/src/modules/launcher/Wox.Core/Plugin/QueryBuilder.cs) decimate user-typed query string and creates a [`Query`](/src/modules/launcher/Wox.Plugin/Query.cs) object. [`Query`](/src/modules/launcher/Wox.Plugin/Query.cs) object contains the action keyword and cleaned query, which is then sent to all plugins.
+
+#### [`Wox.Infrastructure`](/src/modules/launcher/Wox.Infrastructure)
+[`Wox.Infrastructure`](/src/modules/launcher/Wox.Infrastructure) is a .net core project that contains helper classes required for image manipulation and storage by the `PowerLauncher` project and the plugins. [`ImageLoader.cs`](/src/modules/launcher/Wox.Infrastructure/Image/ImageLoader.cs) class is used to load icons for `Win32` program. It also provides caching functionality to speed up image loading for frequently queried programs. 
+
+#### [`Wox.Plugin`](/src/modules/launcher/Wox.Plugin) 
+[`Wox.Plugin`](/src/modules/launcher/Wox.Plugin) contains interfaces that facilitate communication between `PowerLauncher` and plugins. These interfaces have been discussed in detail [here](/doc/devdocs/modules/launcher/architecture.md#flow-of-data-between-viewmodels-and-pluginsmodel). It also contains a helper class for logging. [`Log.cs`](/src/modules/launcher/Wox.Plugin/Logger/Log.cs) provides an abstraction for logging error, information, and output to text files. These files are stored at `%userprofile%/appdata/local/microsoft/powertoys/powertoys run/Logs.`

+# Telemetry
+## Overview
+`PowerLauncher.Telemetry` project contains telemetry events generated by `PowerToys Run.` These event classes are derived from the [`EventBase`](/src/common/ManagedTelemetry/Telemetry/Events/EventBase.cs) class and [`IEvent`](/src/common/ManagedTelemetry/Telemetry/Events/IEvent.cs) class. [`IEvent`](/src/common/ManagedTelemetry/Telemetry/Events/IEvent.cs) class provides the lowest level abstraction, containing attributes such as privacy tags needed for every telemetry data. [`EventBase`](/src/common/ManagedTelemetry/Telemetry/Events/EventBase.cs) class provides a higher-level abstraction, having attributes common to all `PowerToys` telemetry events.
+
+## Events
+The following events are generated by `PowerLauncher`: 
+1. [`LauncherBootEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherBootEvent.cs): This event captures the time taken by `PowerLauncher` to load all plugins, perform cold start, and setup UI environment. 
+2. [`LauncherHideEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherHideEvent.cs): This event is generated when the `PowerLauncher` window is hidden.
+3. [`LauncherColdStateHotkeyEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherColdStateHotkeyEvent.cs): This event logs time from the first Alt+Space press till the `PowerLauncher` window is visible.
+4. [`LauncherFirstDeleteEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherFirstDeleteEvent.cs): This event is generated after the first delete is pressed after `PowerLauncher` is visible.
+5. [`LauncherQueryEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherQueryEvent.cs): This event is generated for every query that is typed in the searchbox. It logs query time, number of results, and query length.
+6. [`LauncherResultActionEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherResultActionEvent.cs): This event is generated when a context menu action is triggered.
+7. [`LauncherShowEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherShowEvent.cs): This event is generated when the `PowerLauncher` window is shown.
+8. [`LauncherWarmStateHotkeyEvent`](/src/modules/launcher/PowerLauncher.Telemetry/Events/LauncherWarmStateHotkeyEvent.cs): This event logs time from the Alt+Space press until the PT Run window is visible.

+
+## Through runner
+- The settings process communicates changes in the UI to most modules using the runner through delegates.
+- More details on this are mentioned in [`runner-ipc.md`](settingsv2/runner-ipc.md).
+
+## PT Run
+- Any changes to the UI are saved by the settings process in the `settings.json` file located within the `/Local/Microsoft/PowerToys/Launcher/` folder.
+- PT Run watches for any changes within this file and updates it's general settings or propagates the information to the plugins, depending on the type of information.
+Eg: The maximum number of results drop down updates the maximum number of rows in the results list which updates the general settings of PT Run whereas the drive detection checkbox details are dispatched to the indexer plugin.
+
+## Keyboard Manager
+- The Settings process and keyboard manager share access to a common `default.json` file which contains information about the remapped keys and shortcuts.
+- To ensure that there is no contention while both processes try to access the common file, there is a named file mutex. 
+- The settings process expects the keyboard manager process to create the `default.json` file if it does not exist. It does not create the file in case it is not present.

+
+### 1. Folder Naming structure
+- Each of the modules has a folder within the `Local/Microsoft/PowerToys` directory which contains the module configurations within the `settings.json` file. The name of this folder must be the same across settingsv1 and settingsv2. 
+- The name of the settings folder for each powertoy is the same as the `ModuleName`. It is set within each of the viewModel files. This name must not be changed to ensure that the user configurations for each of the powertoys rolls over on update.

+### 2. Communication with runner
+- The status of each of the modules is communicated with the runner in the form of a json object. The names of all the powerToys is set in the [`EnableModules.cs`](src/core/Microsoft.PowerToys.Settings.UI.Library/EnabledModules.cs) file. The `JsonPropertyName` must not be changed to ensure that the information is dispatched properly to all the modules by the runner.

+### ImageResizer anomaly
+All the powertoys have the same folder name as well as JsonPropertyName to communicate information with the runner. However that is not the case with ImageResizer.

+# Inter-Process Communication with Runner
+
+The Settings v2 process uses two way IPC to communicate with the runner process.
+
+## Initialization
+- On the settings' side, the two way IPC delegates are contained with the [`ShellPage.xaml.cs`](/src/core/Microsoft.PowerToys.Settings.UI/Views/ShellPage.xaml.cs) file. The delegates are static and the views for all the powerToys send the ipc information to the viewmodels as `ShellPage.DefaultSndMSGCallBack`.
+- These delegates are initialized within the [`Mainwindow.xaml.cs`](/src/core/Microsoft.PowerToys.Settings.UI.Runner/MainWindow.xaml.cs) file in the `Settings.Runner` project.
+
+
+## Types of IPC delegates
+- There are three types of delegates for the settings to communicate with the runner:
+1. `SendDefaultMessage` - This is used by all the viewmodels to communicate changes in the UI to the runner so that the information can be dispatched to the modules.
+2. `RestartAsAdmin`
+3. `CheckForUpdates`
+
+## Sending information to runner
+- The settings process communicates with the runner by using the delegates defined within the [`ShellPage.xaml.cs`](/src/core/Microsoft.PowerToys.Settings.UI/Views/ShellPage.xaml.cs) file.
+- Depending on the type of object sending the information, the json is created accordingly.
+- If any information has been modified by the user in the GeneralSettings page, then the json file sent to the runner has the name set to `general`, whereas if any information has been modified by the user in any powertoy related settings page, the name of the json file being communicated with the runner is set to `powertoy`.
+
+## Receiving information from runner
+- The `ShellPage`object has a `IPCResponseHandleList` which is a list of functions which handle IPC responses. 
+
+```csharp
+// receive IPC Message
+Program.IPCMessageReceivedCallback = (string msg) =>
+{
+    if (ShellPage.ShellHandler.IPCResponseHandleList != null)
+    {
+        try
+        {
+            JsonObject json = JsonObject.Parse(msg);
+            foreach (Action<JsonObject> handle in ShellPage.ShellHandler.IPCResponseHandleList)
+            {
+                handle(json);
+            }
+        }
+        catch (Exception)
+        {
+        }
+    }
+};
+```
+
+- Whenever any information is sent from the runner each of the functions in the handle list perform their action on that json object.
+- One example of where information sent from the runner is being processed by the settings is in [`GeneralPage.xaml.cs`](/src/core/Microsoft.PowerToys.Settings.UI/Views/GeneralPage.xaml.cs) when the user clicks the check for updates button. The information displayed after, such as the user has the latest version installed is a result of this handle.

+# Settings Utilities
+
+- Abstractions for each of the file/folder related operations are present in [`SettingsUtils.cs`](src/core/Microsoft.PowerToys.Settings.UI.Library/SettingsUtils.cs).
+- To reduce contention between the settings process and runner while trying to access the `settings.json` file of any powertoy, the settings process tries to access the file only when it needs to load the information for the first time. However, there is still no mechanism in place which ensures that both the settings and runner processes do not access the information simultaneously leading to `IOExceptions`.
+
+## Utilities
+
+### `GetSettings<T>(powertoy, filename)`
+
+- The GetSettings function tries to read the file in the powertoy settings folder and creates a new file with default configurations if it does not exist.
+- Ideally this function should only be called by the [`SettingsRepository`](src/core/Microsoft.PowerToys.Settings.UI.Library/SettingsRepository`1.cs) which would be accessed only when a powertoy settings object is being loaded for the first time.
+- The reason behind ensuring that it is not accessed elsewhere is to avoid contention with the runner during file access.
+- Each of the objects which are deserialized using this function must implement the `ISettingsConfig` interface.

It contains the parent display window and corresponding code is present in [`MainWindow.xaml.`](/src/core/Microsoft.PowerToys.Settings.UI.Runner/MainWindow.xaml) [`Microsoft.PowerToys.Settings.UI`](/src/core/Microsoft.PowerToys.Settings.UI.Library) is UWP applications and contains views for base navigation and modules. Fig 1 provides a description of the UI controls hierarchy and each of the controls have been summarized below : 
+- [`MainWindow.xaml`](/src/core/Microsoft.PowerToys.Settings.UI.Runner/MainWindow.xaml) is the parent WPF control.
+- `WindowsXamlHost` control is used to host UWP control to [`MainWindow.xaml`](/src/core/Microsoft.PowerToys.Settings.UI.Runner/MainWindow.xaml)  parent control.
+- [`ShellPage.xaml`](/src/core/Microsoft.PowerToys.Settings.UI/Views/ShellPage.xaml) is a UWP control, consisting of a side navigation panel with an icon for each module. Clicking on a module icon loads the corresponding `setting.json` file and displays the data in the UI.

+# Viewmodels
+The viewmodels are located within the [`Microsoft.PowerToys.Settings.UI.Library`](/src/core/Microsoft.PowerToys.Settings.UI.Library) project.
+
+## Components
+- Each viewmodel takes in the general `settingsRepository`, the `moduleSettingsRepository` if it exists and the delegates for IPC communication.
+- The general `settingsRepository` contains the general configurations of all powertoys whereas the `moduleSettingsRepository` is specific to the module. This is to ensure that the configuration details are shared amongst the viewmodels without having to re-open the `settings.json` file.
+- Whenever there is a change in the UI, the `OnPropertyChanged` event is invoked and the viewmodel sends a corresponding IPC message to the runner which would perform the designated action such as dispatching the change to the modules or enabling/disabling the powertoy etc.
+
+#### Difference between viewmodels
+- The [`GeneralViewModel`](/src/core/Microsoft.PowerToys.Settings.UI.Library/ViewModels/GeneralViewModel.cs) is different from the rest of the view models with regard to the IPC communication wherein it sends special IPC messages to the runner to check for updates and to restart as admin.
+- Each of the powerToy viewmodels have two types of IPC communications, one for the general status of the powerToy and the other for communication powerToy specific change in properties to the runner.
+
+## [`SettingsRepository`](src/core/Microsoft.PowerToys.Settings.UI.Library/SettingsRepository`1.cs)
+- The [`SettingsRepository`](src/core/Microsoft.PowerToys.Settings.UI.Library/SettingsRepository`1.cs) is a generic singleton which contains the configurations for each viewmodel.
+- As it is a generic singleton, there can only be one instance of the settings repository of a particular type. This ensures that all the viewmodels are modifying a common object and a change made in one locations reflects everywhere.
+- The singleton implementation is thread-safe. Unit tests have been added for the same.
+
+### Settings viewmodel anomalies
+- The reason behind using the `SettingsRepository` is to ensure that the settings process does not try to access the `settings.json` files directly but rather does it through this class which encapsulates all the file operations from the viewmodels.
+- However, this could not be expanded to all the viewmodels directly for the following reasons. Some refactoring must be done to unify these cases and to bring them under the same model:
+    - The PowerRename viewmodel does not save the settings configurations in the same format as the rest of the powertoys, ie. {name, version, properties}. However, it only stores the properties directly.
+    - Some viewmodels expect the runner to create the file instead of creating the file themselves, like in keyboard manager.
+    - The colorpicker powertoy creates the `settings.json` within the module. This must be taken care of when encapsulated within the settingsRepository.
+- Currently, all modules use the `SettingsRepository` to access the General Settings config. 
+- However, only Fancyzones, ShortcutGuide and PowerPreview use the `SettingsRepository` to access the module properties.

+# XAML Island Tweaks
+Few tweaks were made to fix issues with Xaml Islands. These tweaks should be removed after migrating to WINUI3. The tweaks are listed below: 
+1. Workaround to ensure XAML Island application terminates if attempted to close from taskbar while minimized:
+```
+private void MainWindow_Closing(object sender, System.ComponentModel.CancelEventArgs e)
+{
+    isOpen = false;
+
+    // XAML Islands: If the window is closed while minimized, exit the process. Required to avoid process not terminating issue - https://github.com/microsoft/PowerToys/issues/4430
+    if (WindowState == WindowState.Minimized)
+    {
+        // Run Environment.Exit on a separate task to avoid performance impact
+        System.Threading.Tasks.Task.Run(() => { Environment.Exit(0); });
+    }
+}
+```
+2. Workaround to hide the XAML Island blank icon in the taskbar when the XAML Island application is loading:
+```
+var coreWindow = Windows.UI.Core.CoreWindow.GetForCurrentThread(); 
+var coreWindowInterop = Interop.GetInterop(coreWindow); 
+Interop.ShowWindow(coreWindowInterop.WindowHandle, Interop.SW_HIDE); 
+```
+3. Workaround to prevent XAML Island failing to render on Nvidia workstation graphics cards:
+```
+ // XAML Islands: If the window is open, explicitly force it to be shown to solve the blank dialog issue https://github.com/microsoft/PowerToys/issues/3384 
+ if (isOpen) 
+ { 
+     Show(); 
+ } 
+ ```

-# Shared hooks
-
-To minimize the performance impact on the machine only `runner` installs global hooks, passing the events to registered callbacks in each PowerToy module.
-
-When a PowerToy module is loaded, the `runner` calls the [`get_events()`](/src/modules/interface/powertoy_module_interface.h#L40) method to get a NULL-terminated array of NULL-terminated strings with the names of the events that the PowerToy wants to subscribe to. A `const wchar_t*` string is provided for each of the event names.
-
-Events are signalled by the `runner` calling the [`signal_event(name, data)`](/src/modules/interface/powertoy_module_interface.h#L53) method of the PowerToy module. The `name` parameter contains the NULL-terminated name of the event. The `data` parameter and the method return value are specific for each event.
-
-Currently supported hooks:
- * `"ll_keyboard"` - [Low Level Keyboard Hook](#low-level-keyboard-hook)
- * `"win_hook_event"` - [Windows Event Hook](#windows-event-hook)
-
-## Low Level Keyboard Hook
-
-This event is signaled whenever the user presses or releases a key on the keyboard. To subscribe to this event, add `"ll_keyboard"` to the table returned by the `get_events()` method.
-
-The PowerToys runner installs low-level keyboard hook using `SetWindowsHookEx(WH_KEYBOARD_LL, ...)`. See [this MSDN page](https://docs.microsoft.com/en-us/previous-versions/windows/desktop/legacy/ms644985(v%3Dvs.85)) for details.
-
-When a keyboard event is signaled and `ncCode` equals `HC_ACTION`, the `wParam` and `lParam` event parameters are passed to all subscribed clients in the [`LowlevelKeyboardEvent`](/src/modules/interface/lowlevel_keyboard_event_data.h#L38-L41) struct.
-
-The `intptr_t data` event argument is a pointer to the `LowlevelKeyboardEvent` struct.
-
-A non-zero return value from any of the subscribed PowerToys will cause the runner hook proc to return 1, thus swallowing the keyboard event.
-
-Example usage, that makes Windows ignore the L key:
-
-```c++
-virtual const wchar_t** get_events() override {
-  static const wchar_t* events[2] = { ll_keyboard,
-                                      nullptr };
-  return events;
-}
-
-virtual intptr_t signal_event(const wchar_t* name, intptr_t data) override {
-  if (wcscmp(name, ll_keyboard) == 0) {
-    auto& event = *(reinterpret_cast<LowlevelKeyboardEvent*>(data));
-    // The L key has vkCode of 0x4C, see:
-    // https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes
-    if (event.wParam == WM_KEYDOWN && event.lParam->vkCode == 0x4C) {
-      return 1;
-    } else {
-      return 0;
-    }
-  } else {
-    return 0;
-  }
-}
-```
-
-## Windows Event Hook
-
-This event is signaled for [a range of events](https://docs.microsoft.com/pl-pl/windows/win32/winauto/event-constants). To subscribe to this event, add `"win_hook_event"` to the table returned by the `get_events()` method. See [this MSDN doc](https://docs.microsoft.com/pl-pl/windows/win32/api/winuser/nf-winuser-setwineventhook) for details.
-  
-The `intptr_t data` event argument is a pointer to the [`WinHookEvent`](/src/modules/interface/win_hook_event_data.h#L43-L50) struct.
-
-The return value of the event handler is ignored.
-
-Example usage, that detects a window being resized:
-
-```c++
-virtual const wchar_t** get_events() override {
-  static const wchar_t* events[2] = { win_hook_event,
-                                      nullptr };
-  return events;
-}
-
-virtual intptr_t signal_event(const wchar_t* name, intptr_t data) override {
-  if (wcscmp(name, win_hook_event) == 0) {
-    auto& event = *(reinterpret_cast<WinHookEvent*>(data));
-    switch (event.event) {
-    case EVENT_SYSTEM_MOVESIZESTART:
-      size_start(event.hwnd);
-      break;
-    case EVENT_SYSTEM_MOVESIZEEND:
-      size_end(event.hwnd);
-      break;
-    default:
-      break;
-    }
-  }
-  return 0;
-}
-```
-
-Taking too long to process the events has negative impact on the whole system performance. To address this, the events are signaled from a different thread, not from the event hook callback itself.

 - We use [`.clang-format`](https://github.com/microsoft/PowerToys/blob/master/.clang-format) style file to enable automatic code formatting. You can [easily format source files from Visual Studio](https://devblogs.microsoft.com/cppblog/clangformat-support-in-visual-studio-2017-15-7-preview-1/). For example, `CTRL+K CTRL+D` formats the current document.
-- If you prefer another text editor or have ClangFormat disabled in Visual Studio, you could invoke [`format_sources`](https://github.com/microsoft/PowerToys/blob/master/format_sources.ps1) powershell script from command line. It gets a list of all currently modified files from `git` and invokes clang-format on them.
