Undoing and redoing actions from the keyboard

The UndoManagerKeyInteractor interactor allows application users to use the keyboard to undo and redo graph actions. Users can apply the undo and redo actions for as many time as there are undo and redo changes stored in the Undo Manager, but the key presses must be repeated for each change that to be undone or redone.
The following table lists the keyboard key combinations that the UndoManagerKeyInteractor assigns by default to Undo Manager functions:
Action Description Default key combination
undo Calls the undoAction function of the Undo Manager. Ctrl+Z
redo Calls the redoAction function of the Undo Manager. Ctrl+Y
