There are two different config files. In your module folder (sites/all/modules/fckeditor) there is also an fckeditor.config.js which provides the Drupal presets. You could clone the DrupalBasic preset and edit it to do what you want.

Thanks for the response. But after looking at the fckeditor.config.js file, I see references to the FontFormat, but nothing related to the individual items that are supposed to be in the list. I'm not trying to change the FCKEditor menubar so much as changing the items that are populated in that one particular widget.

Oh, sorry, I must have misread your OP. I would think that editing the FontFormats would do it...

Did you clear your Drupal and Browser cache?

I cleared the browser cache. I didn't clear any Drupal cache because since I'm still in development I haven't enabled any caching for performance. Is there a certain amount of caching that Drupal does even if the caching in the performance settings is not enabled?

I checked the caching settings in the performance settings admin page. Performance caching was indeed disabled, but I went ahead and clicked the "clear cache" button at the bottom of the page anyway. No difference. Even cleared browser cache again after clearing drupal cache.

Is there another place I should go to clear cached drupal pages?
