Keyboard Keys and Key Code Values

The following tables list all the keys on a standard keyboard and the corresponding key code values and ASCII key code values that are used to identify the keys in ActionScript:

You can use key constants to intercept the built-in behavior of keypresses. For more information on the on() handler, see on handler in the ActionScript 2.0 Language Reference. To capture key code values and ASCII key code values using a SWF file and key presses, you can use the following ActionScript code:

var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
    trace("DOWN -> Code: " + Key.getCode() + "\tACSII: " + Key.getAscii() + "\tKey: " + chr(Key.getAscii()));
};
Key.addListener(keyListener);

For more information on the Key class, see Key in ActionScript 2.0 Language Reference. To trap keys when you test a SWF file in the authoring environment (Control > Test Movie), make sure that you select Control > Disable Keyboard Shortcuts.
