Key 373
Example
The following example creates a new listener object and defines a function for
onKeyDown and
onKeyUp. The last line uses addListener() to register the listener with the Key object so that
it can receive notification from the key down and key up events.
var myListener:Object = new Object();
myListener.onKeyDown = function () {
trace ("You pressed a key.");
}
myListener.onKeyUp = function () {
trace ("You released a key.");
}
Key.addListener(myListener);
