When this MoveFocusByKeyExit method is called, focus will move. The keys that are involved are ExitKeys.CharInput, ExitKeys.CtrlRight, ExitKeys.NextControl, ExitKeys.Right, and ExitKeys. Tab moves the focus forward. Other ExitKeys move the focus backward. Notes for Inheritors: The base method must be invoked when overriding it in the inherited class; otherwise, the focus does not move.
