How to add / remove buttons from FCKeditor

I'm sure this question has been asked a hundred times over, but how do you add/remove buttons from the editor.

I wend into fckconfig.js and found the ToolbarSets["Default"] and ToolbarSets["Basic"], but when I remove a button from the array, it still shows up. I cleared my browser cache, and still get the same result.

Am I missing something?

TIA,

Tom

P.S.>>>>

Question, who mods this forum?

It just seems like it could use a little better organization/structure, and totally is begging for a FAQ sticky at the top of the major forums (that includes links to helpful threads). I'd do more searches for answers if there were actually threads with more than one post.
