Is it possible (and not too difficult) to customize a toolbar, made from elements of other FCKeditor 2.4.1 toolbars? I would like my custom toolbar to appear in the Show Custom Editor Options > Editor Toolbar View Options (section), and be assigned to All Users.

I would like to have a simple toolbar that has:

Bold
Italic
Insert/Remove Numbered List
Insert/Remove Bulleted Lists
Insert/Edit Link
Remove Link
Undo/Redo

By disabling all toolbars, I get the above, except not the Undo/Redo function/buttons.

So another way to look at this is that I want to add Undo/Redo to the state of FCKeditor when no toolbars are active.

Thank you. This was exactly the level of kick-start I needed to make my own toolbar. Actually, the FCKeditor 'Basic' toolbar was everything I was looking for, except it was missing Undo/Redo. Here's exactly what I did to Add Undo and Redo to the Basic toolbar:

Make a backup/copy of the file: ...\Providers\HtmlEditorProviders\Fck\Custom\fckconfig.js
Edit fckconfig.js
Find the 'Basic' toolbar definition:

FCKConfig.ToolbarSets["Basic"] = [
 ['Bold','Italic','-','OrderedList','UnorderedList','-','Link','Unlink','-','About']
] ;

Insert the Undo and Redo buttons:

FCKConfig.ToolbarSets["Basic"] = [
 ['Bold','Italic','-','OrderedList','UnorderedList','-','Link','Unlink','-','Undo','Redo','-','About']
] ;

Save fckconfig.js and exit.

Make a backup/copy of .../web.config
Edit web.config
Find the FCKeditor section that includes:

AvailableToolBarSets="DNNDefault,Default,NoGallery,Basic"
     DefaultToolbarSet="DNNDefault"
     DefaultImageGallerySkin="Default"
     DefaultFlashGallerySkin="Default"
     DefaultLinksGallerySkin="Default"
     FCKDebugMode="false"
     UseFCKSource="false"
     OptionsOpenMode="ShowModalDialog"
     CustomOptionsDialog="Admin" />

Change: DefaultToolbarSet="Basic"

Save web.config and exit.
