我加了一個 timerkey2 ，當放開a鍵時，它會倒播回第一影格。
如果意思不對，請告訴我再修改。
如下：(有//====記號處，就是我修改的地方)

stop();

stage.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, reportKeyUp);

//宣告key1自帶timer
var timerkey1:Timer = new Timer(60,0);
timerkey1.addEventListener(TimerEvent.TIMER , tick_key1 );
var timerkey2:Timer = new Timer(60,0);//====
timerkey2.addEventListener(TimerEvent.TIMER , tick_key2 );//====

//宣告key1計時變數;
var timeKey1NUM:Number = 0;

//------------ ( 鍵盤按下事件 ) -----------------
function reportKeyDown(event:KeyboardEvent):void
{
    //按下鍵盤A時
    if (event.keyCode == 65)
    {

        timerkey1.start();

        //觸發隨機只在按下第一次執行;
        if ( timeKey1NUM == 0 )
        {
            CMC1.x = stage.stageWidth * (int(Math.random() * 10) / 10);
            CMC1.y = stage.stageHeight * (int(Math.random() * 10) / 10);
        }
    }
}

//------------ ( 鍵盤放開事件 ) -----------------
function reportKeyUp(event:KeyboardEvent):void
{
    if (event.keyCode == 65)
    {
//        timeKey1NUM = 0;//====

//        CMC1.gotoAndStop(1);//====
        timerkey1.stop();
        timerkey1.reset();
        timerkey2.start();//====
    }
}

//當key1按下時 觸發此時間迴圈計時
function tick_key1(event:TimerEvent):void
{
    timeKey1NUM +=  1;

    if ( timeKey1NUM >=1 )
    {
        CMC1.visible = true;
        CMC1.gotoAndStop( timeKey1NUM );
    }
    else
    {
        CMC1.visible = false;
    }
}
//===============================
//當key1放開時 觸發此時間迴圈計時
function tick_key2(event:TimerEvent):void
{
    timeKey1NUM -=  1;

    if ( timeKey1NUM >=1 )
    {
        CMC1.alpha = 1/timeKey1NUM
        CMC1.gotoAndStop( timeKey1NUM );
    }
    else
    {
        timeKey1NUM = 0;
        CMC1.alpha = 1
        CMC1.gotoAndStop(1);
        timerkey2.stop();
        timerkey2.reset();
    }
}
