keyconfig.uc.js脚本如何自定义快捷键啊？

keyconfig.uc.js脚本如何自定义快捷键啊？弄了好久，1个也没成功过，各位大侠帮帮忙。指点下，谢了先~！！！

下面是该脚本代码：

// ==UserScript==
// @name           keyconfig_Modoki.uc.js
// @namespace      http://d.hatena.ne.jp/Griever/
// @include        main
// ==/UserScript==
(function(){
var keymap = {
'8':'backspace','9':'tab','12':'tenkey5','13':'enter','16':'shift','17':'ctrl','18':'alt',
'19':'pausebreak','20':'shift+capslock','27':'esc','32':'space',
'33':'pageup','34':'pagedown','35':'end','36':'home',
'37':'left','38':'up','39':'right','40':'down','45':'insert','46':'delete',

};

function $(id){ return document.getElementById(id)}

function keyconfig(e){
	if (/^(input|textarea|select|textbox)$/i.test(e.target.localName)) return;
	var keycode = e.keyCode;
	if (keycode >= 16 && keycode <= 18) return;
	var command = keymap[keycode] + (e.ctrlKey?'+ctrl':'') + (e.shiftKey?'+shift':'') + (e.altKey?'+alt':'');

/* キーを小文字、スペース無し、+で連結、ctrl・shift・altの順で  小写关键字+ctrl・shift・alt+命令的顺序添加 */
	switch(command){//uc.js脚本默认的快捷键设置
		case 'z' : $("Browser:Back").doCommand(); break;//后退

		case '+' : $("cmd_fullZoomEnlarge").doCommand(); break;//缩放 - 放大

			//keyconfig扩展的快捷键设置和用户自定义设置添加到下面：

		case 'f3': gFindBar.onFindAgainCommand(false); break;//查找下一个
		case '0': FullZoom.reset(); break;//缩放 - 重置
		case 'f5': if (event.shiftKey) BrowserReloadSkipCache(); else BrowserReload(); break;//刷新
		case "t+shift+ctrl": undoCloseTab(); break;//撤销关闭标签页
		case "r+ctrl": if (event.shiftKey) BrowserReloadSkipCache(); else BrowserReload(); break;//重新载入
		case "f5+ctrl": BrowserReloadSkipCache(); break;//重新载入(忽略缓存)
		case "": var tab = gBrowser.mCurrentTab.boxObject.previousSibling;
if(tab) gBrowser.removeTab(tab); break;//关闭左边标签页

		default: return;

	e.preventDefault();
}

gBrowser.mPanelContainer.addEventListener('keydown', keyconfig, false);
})();

小写关键字+ctrl・shift・alt+命令的顺序添加
这不是有么，命令代码写在case里。

web123lai：小写关键字+ctrl・shift・alt+命令的顺序添加

可以示范一个我看下吗？我好有个范本，用我上面的代码，我对这东西没什么概念，不懂啊~！！！

本人实验成功。alt+a打开 附加组件窗口。
代码如附件.

case "z+ctrl": gBrowser.undoRemoveTab(); break;//撤销关闭标签页
case "f5+ctrl": BrowserReloadSkipCache(); break;//重新载入(忽略缓存)
case 'f4': Application.restart(); baeak;//重启FF
case 's+alt': Components.classes["@mozilla.org/file/directory_service;1"].
getService(Components.interfaces.nsIProperties).get("ProfD", Components.interfaces.nsILocalFile).launch(); break;//打开配置文件夹
case 'a+ctrl+shift': toOpenWindowByType('Add-ons:manager',
'chrome://mozapps/content/extensions/extensions.xul'); break;//附加组件对话框
case 'w+alt': Cc['@mozilla.org/browser/browserglue;1'].getService(Ci.nsIBrowserGlue).sanitize(window); TMP_Sanitizer.tryToSanitize(); break;//清空临时文件
        case "o+ctrl+shift": openPreferences(); break;//工具-选项对话框
        case "c+alt":var tab = gBrowser.mCurrentTab; gBrowser.removeTab(tab); break;//关闭当前标签
