在Javascript中使用特殊键进行键绑定

我想知道是否可以使用macbook pro用于音乐控制的特殊键，并用javascript绑定它们？ 示例键：播放/暂停、下一步、后退

我试图这样做，以修改greasemonkey脚本，如果这有帮助的话

这是当前的代码

HotKeys.bindings['/'] = HotKeys.activateSearch;
HotKeys.bindings['p'] = HotKeys.playPrev;
HotKeys.bindings['n'] = HotKeys.playNext;
HotKeys.bindings['k'] = HotKeys.selectPrev;
HotKeys.bindings['j'] = HotKeys.selectNext;
HotKeys.bindings['o'] = HotKeys.playSelected;
HotKeys.bindings['v'] = HotKeys.openBlog;
HotKeys.bindings['s'] = HotKeys.toggleFavorite; 

HotKeys.keyBindings[27] /*ESC*/ = HotKeys.deactivateSearch;

只需将按键事件侦听器应用于文档，并将事件记录到控制台，以便查看它是否已注册。与此类似：
