Hmm, that I got not working (most probably due to my limited lisp
knowledge; tried a regexp replace ala "\0_\1_\2.pdf" and also using
(format ...)). 

That is, I actually need to perform a few transformations on the key
to get the filename. However, it still works quite nicely when using
the following bibtex-generate-url-list entry:

     (("=key=" . ".*")
      ("=key=" ".*" jk/bibtex-pdf-name))

and a simple transformation function

(defun jk/bibtex-pdf-name (key)
  "Determine filename in PDF databse from bibtex key.

This function determines the filename corresponding to the current entry.
"
  (progn
    (subst-char-in-string (string-to-char ":") (string-to-char "_") key t)
    (concat jk/bibtex-pdf-location "/" (substring key 0 1) "/" key  ".pdf")))


I am sure someone could do that using a smart regexp replace, but this
I understand;) I do assume that a regexp/replace solution might be
faster?

No problem for me. (But I do know some people who will only use this
with clickable keys...)


Thanks for your help.
