Usage

 someListener  .onKeyDown 

Description
Listener; notified when a key is pressed. To use onKeyDown you must create a listener object. You can then define a function for onKeyDown and use the addListener method to register the listener with the Key object, as in the following:

someListener = new Object();
someListener.onKeyDown = function () { ... };
Key.addListener(someListener);

Listeners enable different pieces of code to cooperate because multiple listeners can receive notification about a single event.
