Enabling TinyMCE Plugins
Defining the TinyMCE Plugin Resources
You will need to define the TinyMCE plugin resources (e.g. editor_plugin.js) in a web resource module with an added context of 'wysiwyg-editor'. Below is an example plugin descriptor for the TinyMCE Search & Replace plugin.
Configuring TinyMCE Plugin Settings
AJS.Editor.Adapter.addTinyMcePluginInit. The following code enables the search/replace plugin and adds the search and replace buttons to the second row of the toolbar.
Please note that if you are enabling several buttons on the toolbar, the buttons may not appear on pages using the Clickr theme. The theme has a fixed screen width, hence it is better to display the buttons on the second row of the toolbar.
