# ViewDocumentTabEvent

typedef

Event fired when the user presses a tab key.

Introduced by [`TabObserver`](module_engine_view_observer_tabobserver-TabObserver.md).

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