MACROMEDIA FLASH 8-FLASH LITE 2.X ACTIONSCRIPT LANGUAGE - Onkeyup (Key.onkeyup Event Listener); PGDN (Key.pgdn Property)

384 ActionScript classes
onKeyUp (Key.onKeyUp event listener)
onKeyUp = function() {}
Notified when a key is released. To use onKeyUp, you must create a listener object. You can
then define a function for
onKeyUp and use addListener() to register the listener with the
Key object, as shown in the following example:
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
trace("DOWN -> Code: "+Key.getCode()+"\tACSII: "+Key.getAscii()+"\tKey:
"+chr(Key.getAscii()));
};
keyListener.onKeyUp = function() {
trace("UP -> Code: "+Key.getCode()+"\tACSII: "+Key.getAscii()+"\tKey:
"+chr(Key.getAscii()));
};
Key.addListener(keyListener);
Listeners enable different pieces of code to cooperate because multiple listeners can receive
notification about a single event.

Example
The following example rotates a movie clip called
car_mc when you press the Page Down and
Page Up keys.
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
if (Key.isDown(Key.PGDN)) {
car_mc._rotation += 5;
} else if (Key.isDown(Key.PGUP)) {
car_mc._rotation -= 5;
}
};
Key.addListener(keyListener);
