我目前正在开发和 AIR 应用程序来检测组合键的命令键，目前我有这样的东西

this.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);

protected function onKeyUp(event:KeyboardEvent):void
{
  if(event.ctrlKey){
    switch(event.keyCode){
      case Keyboard.C:
      trace("need to copy");
      break;
    }
  }
}

根据文档 event.ctrlKey，应该检测 mac 上的命令和控制键，如果我按下组合控制 + C 作品，但如果我不使用命令 + c 什么，我也尝试过 

event.commandKey

我以为内置菜单可能给我带来了一些麻烦，然后我将其删除，但仍然没有，我错过了什么？谢谢你的帮助

我也遇到了同样的问题，并通过为剪贴板键添加本机菜单事件来解决此问题。正如您所说，“event.ctrlKey”不适用于 MAC，而“命令键”与 C(copy)、V(paste)、X(cut)、W(close)、M(minimize) 结合使用将始终收听AIR 应用程序的本机菜单事件（buildIn 菜单事件）。所以我添加了菜单选择事件。
