# ViewDocumentKeyUpEvent

typedef

Fired when a key has been released.

Introduced by [`KeyObserver`](module_engine_view_observer_keyobserver-KeyObserver.md).

Note that because [`KeyObserver`](module_engine_view_observer_keyobserver-KeyObserver.md) is attached by the [`EditingView`](module_engine_view_view-EditingView.md) this event is available by default.
