这段代码是使用 ActionScript 2.0 编写的，而在 ActionScript 2.0 中，Key 类是用来检测键盘事件的，但是它不支持检测单独的按键。如果想要检测单独的按键，可以使用 Key.getCode() 方法来获取按键的 ASCII 码值，然后进行比较。

在这段代码中，你可以修改如下部分：

if (Key.isDown(Key.H)) {
    // 从舞台上删除该剪辑
    this.removeMovieClip();
    return;
    this._x = _root._xmouse;
    this._y = _root._ymouse;
}

改为：

if (Key.getCode() == 72) { // H键的ASCII码值为72
    // 从舞台上删除该剪辑
    this.removeMovieClip();
    return;
    this._x = _root._xmouse;
    this._y = _root._ymouse;
}

这样就可以检测到按下 H 键的事件了。

可以在`target_mc.onMouseMove`事件处理程序中添加按键检测，如果检测到按下了“h”键，则使用`removeMovieClip()`方法将该剪辑从舞台上删除。代码如下：

target_mc.onMouseMove = function() {
    // 检测是否按下了"h"键
    if(Key.isDown(Key.H)) {
        // 从舞台上删除该剪辑
        this.removeMovieClip();
        return;
    }
    this._x = _root._xmouse;
    this._y = _root._ymouse;
    // 检查图像是否与其他图像重叠，并根据需要更新其透明度
    for (var j = 1; j <= 9; j++) {
        var other_mc:MovieClip = _root["tu" + j];
        if (target_mc != other_mc && target_mc.hitTest(other_mc)) {
            target_mc._alpha = 50;
            return;
        }
    }
    target_mc._alpha = 100;
};
