Hi Uwe,

I didn't test it, but I'm pretty sure about the syntax ;-)  If you look
closer at my code above for RefTeX, you'll see that it uses backquote `
and not a quote '.  See here for why[1].

If you want to put that stuff in your .emacs, try something like this:

--8<---------------cut here---------------start------------->8---
(with-eval-after-load "latex"
  (add-to-list 'LaTeX-label-alist '("titledquestion" . LaTeX-exam-label)))

(require 'reftex)

(add-to-list 'reftex-label-alist
             `("titledquestion" ?x
               ,(concat LaTeX-exam-label "%f:")
               "~\\ref{%s}" nil ("ejercicio") ))
--8<---------------cut here---------------end--------------->8---

I'm not sure if using ?t is a good idea since it is hard-coded in RefTeX
for tables.

Best, Arash
