KeyTrigger (Windows Phone)

You can use the KeyTrigger trigger in a Windows Phone project to invoke an action based on a combination of keys pressed on the keyboard (a keyboard shortcut).

To add a KeyTrigger to a Windows Phone project

1. In the Assets panel, click Behaviors, and then drag the behavior that you want onto the object that you want to apply the behavior to. The Trigger category appears in the Properties panel.

2. In the Trigger category, next to TriggerType (EventTrigger), click New.

3. In the SourceName dialog box, use the Artboard element picker to pick the element from a list of elements that appear on the artboard.

4. In the SourceObject dialog box, select the element that you want to define a keyboard shortcut for. By default, the SourceObject is the element that contains an action. Use the Artboard element picker to select the element that you want directly on the artboard or click Data bind  to bind the data.

5. In the FiredOn drop-down list, specify either KeyDown or KeyUp:

   • KeyDown   Triggers the behavior when the keyboard shortcut is pressed.

   • KeyUp   Triggers the behavior when the keyboard shortcut is released.

6. In the Key menu, click the key that the user will press to fire the trigger.

7. In the Modifiers menu, click the modifier key that the user will press to fire the trigger.
