# CropAndLock Module

## Synopsis

Manages configuration for the Crop And Lock utility, which crops and locks portions of windows.

## Description

The `CropAndLock` module configures PowerToys Crop And Lock, a utility that allows you to crop a portion of any window and keep it visible as a thumbnail. This is useful for monitoring specific parts of applications, keeping reference information visible, or focusing on particular UI elements.

## Properties

The CropAndLock module supports the following configurable properties:

### Hotkey

Sets the keyboard shortcut to activate Crop And Lock for the active window.

**Type:** object  
**Properties:**

- `win` (boolean) - Windows key modifier.
- `ctrl` (boolean) - Ctrl key modifier.
- `alt` (boolean) - Alt key modifier.
- `shift` (boolean) - Shift key modifier.
- `code` (integer) - Virtual key code.
- `key` (string) - Key name.

**Default:** `Win+Ctrl+Shift+T`

### ReparentHotkey

Sets the keyboard shortcut to change the parent window of a cropped thumbnail.

**Type:** object (same structure as Hotkey)

### ThumbnailOpacity

Sets the opacity of cropped thumbnails (0-100).

**Type:** integer  
**Range:** `0` to `100`  
**Default:** `100`

## Examples

### Example 1 - Configure basic settings with direct execution

This example sets the Crop And Lock hotkey and thumbnail opacity.

```powershell
$config = @{
    settings = @{
        properties = @{
            ThumbnailOpacity = 90
        }
        name = "CropAndLock"
        version = "1.0"
    }
} | ConvertTo-Json -Depth 10 -Compress

PowerToys.DSC.exe set --resource 'settings' --module CropAndLock --input $config
```

### Example 2 - Configure hotkeys with DSC

This example configures custom hotkeys for cropping and reparenting.

```bash
dsc config set --file cropandlock-hotkeys.dsc.yaml
```

```yaml
# cropandlock-hotkeys.dsc.yaml
$schema: https://aka.ms/dsc/schemas/v3/bundled/config/document.json

      settings:
        properties:
          Hotkey:
            win: true
            ctrl: true
            shift: true
            alt: false
            code: 84
            key: T
          ThumbnailOpacity: 85
        name: CropAndLock
        version: 1.0
```

### Example 3 - Install and configure with WinGet
