背景：由于我使用的是百度空间，本身百度空间发帖的富文本编辑器并不支持代码高亮，因此最近搞了一个FireFox下的用户脚本，可以通过快捷键设置代码高亮，效果很不错，并且实现了脱离百度空间以及FireFox的环境。
下面就将代码与大家分享（注：此高亮效果即为快捷键设置的结果）

虽然本身cnblogs支持发布代码，但这里只是作为一个效果而已，你可以将它引入到任何blog博客中（这也是我的初衷）。
更新可访问我建立的Google Code：http://code.google.com/p/hotkeyhighlightcode/，里面还有个Demo，你可以本地测试一下效果。
FireFox下UserScript安装地址：http://userscripts.org/scripts/show/34520默认支持百度空间，如果你需要应用到其他博客空间，需要设置Highlight.target参数及userscript应用到网页的规则。
百度空间firefox用户脚本应用到网页的规则：
http://hi.baidu.com/*/creat/blog/
http://hi.baidu.com/*/modify/*
PS：cnblogs的规则如下
http://www.cnblogs.com/*/admin/EditPosts.aspx
1、通过不同的快捷键可设置背景高亮、多种语言关键字的代码多彩高亮，这包括javascript、c#、Css、Java、Php、Sql、Vb等不同语言，并且支持新增（这部分参考了SyntaxHighlighter）。
2、自定义方式更加灵活，包括背景颜色，快捷键设置，多彩颜色，目标窗体，以至于添加更多语言支持，具体可参看注释。
3、支持其他基于iframe富文本编辑器的空间博客（测试中在百度、sohu、cnblogs等博客下工作良好），通过设置目标窗体即可。主要是针对目标框架的设置，即 iframe（因为大部分的富文本编辑器都是基于iframe实现的）。如果仅包含一层iframe，可能会是这样设置Highlight.target = document.getElementsByTagName("iframe")[0].contentWindow（cnblogs就是如此），如有复杂嵌套关系可参考代码中的 百度空间Highlight.target的设置（代码中包含sohu,baidu空间的设置示例），注意iframe嵌套关系。
4、可脱离firefox以脚本方式引入其他任何基于iframe富文本编辑器的站点或blog。
5、代码兼容IE、FireFox.
如果你有什么疑问或需要什么帮助可以留言与我交流。
