    import flash.events.KeyboardEvent;
    
    public class Main extends Sprite

            init();

        {
            stage.addEventListener(KeyboardEvent.KEY_DOWN, aaa);
        }
        
        public function aaa(e:KeyboardEvent):void
        {
            //e.charCode显示输入的字符编码（会区分大小写）
            //forChareCode会将字符编码转义成输入的字符显示出来
            trace(String.fromCharCode(e.charCode));
        }
        
    }
}
