The OnKeyDown method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnKeyDown in a derived class, make sure to call the base class’s OnKeyDown method so that registered delegates receive the event.
