public event KeyEventHandler KeyUp

This event creates an alias for the Keyboard.KeyUp attached event for this class so that KeyUp is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the KeyUp event are attached to the underlying Keyboard.KeyUp attached event and receive the same event data instance.
