Remarks

Most scenarios involving the keyboard are addressed by writing handlers for the key events KeyUp and KeyDown. The Keyboard class is a utility class with only one property, Modifiers. The event data class for KeyUp and KeyDown events reports the primary pressed key corresponding to each raising of a key event. If you want to check whether any modifier keys are also in a pressed state, you can check the Keyboard.Modifiers value from within a mouse event handler.

You might also want to check the Keyboard.Modifiers value when handling mouse events, depending on your application's input design.
