Events are occurrences that the system recognizes, such as mouse clicks or keystrokes.
When an event is received by an application, the first responder in the responder chain is given the chance to deal with it. If the first responder doesn't know what to do with it, the event is passed on, up the responder chain. If no responder deals with the event, it is ignored.
