please help with font-lock-add-keywords

appropriate...)

Hi all,

I'd like to fontify a whole bunch of function names for a project I'm
working on (which uses lisp mode, not emacs-lisp-mode -- for reference,
I'm using GNU emacs 23.1.1).

Almost all of the functions start with the same prefix "qbb-" so that
shouldn't be too hard (though for the examples I've just tried to use
some actual function names to get it to work).  I've done a bunch of web
searching, and haven't figured out a way to make this work.

I've tried all of the following, and none of them work for me...  I
don't claim to be a wizard at this stuff, but thought I had followed the
examples correctly

(font-lock-add-keywords
 'lisp-mode
 '(("\\<\\(qbb-create-image\\|qbb-destroy-image\\)\\>" .
    font-lock-keyword-face)))

(font-lock-add-keywords
 'lisp-mode
 '(("\\<\\qbb-create-image\\)" 2 font-lock-keyword-face t)))

(add-hook 'lisp-mode-hook
          (lambda ()
            (font-lock-add-keywords
             nil
             '(("\\<\\(qbb-create-image\\|qbb-destroy-image\\)\\>" .
                font-lock-keyword-face)))))

I'm sure this can't be as hard as I'm making it -- help, please!

Thanks in advance!
