WebGUI uses TinyMCE for it's embedded editor. What many people dont' know is that there are many more options that one can have available to them in the editor.

1. Login as Admin
2. Go to Asset Manager
3. Go to Root/Import/RichEdit
4. You can modify The Content Manger's Rich Edit or the Forum Rich Edit
5. Select the Options you wish to enable

It is here that you can also set behavior settings.
