Hm I don't remember, why I did this, but what you say makes sense.

Ok my bad. I forgot to mention my reftex setting :'(

(defun my-reftex-label-alist-6 ()
"Sets reftex-label to have a 6th entry"
(interactive)
(setq reftex-label-alist
("thm" ?h "thr:%f:" "~\\ref{%s}" t   ("Theorem" "Theor." "Th."))))

Or even

(defun my-reftex-label-alist-7 () 
  "Sets reftex-label to have a 7th entry"
  (interactive)
  (setq reftex-label-alist
                  ("thm" ?h "thr:%f:" "~\\ref{%s}" t   ("Theorem"
  "Theor." "Th.")-1)))

And I put them into the corresponding hook.

That is better than my solution.

That sounds cool and would be appreciate by the users, I think!
Thanks
