第一步：需要书写你的插件文件，这里必需留意你的目次布局，默认的插件路径是..../editor/plugins/ 。为了利便起见我们不改变默认路径，先在这个目次下建设一个存放插件的文件夹，这里我们起名为formatcommands。
然后我们在此目次下建设一个fckplugin.js，记着这里插件的名字必需为这个名字（巨细写也要一致），然后我们在建设一个语言包文件夹lang，最后把需要的图标文件也放在与插件文件fckplugin.js同目次下，详细的文件目次请看图：
增补说明一下：lang文件夹下面是语言包文件，这里我建设了一个en.js 留意 en是国别码都是小写的，假如要是中文可以写成 zh-cn.js
en.js 的源码为：

FCKLang.Format168Btn = 'format';
这个是为了给出鼠标悬停到按钮上的提示。插件文件的源代码为：

第二步：修改fck默认的设置文件
直接修改默认的设置文件 fckconfig.js。从FCKeditor文件夹下找到fckconfig.js。找到下面这句：
FCKConfig.PluginsPath = FCKConfig.BasePath + 'plugins/' ;然后增加：
FCKConfig.Plugins.Add('formatcommands') ;
