flash脚本中如何捕获键盘键值并转换为其他值

主场景帧上写
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
if (Key.getCode() == Key.ENTER) {
trace ("Virtual key code: "+Key.getCode()+" (ENTER key)");
//Key.getCode()就是你按的键值
}
else {
trace("Virtual key code: "+Key.getCode());
}
};
Key.addListener(keyListener);
