I'm writing my thesis using ConTeXt but I'm not satisfied with the way the
publication list is displayed.
I'd like to display the key, in brackets, in front of every publication in
the list (i.e. replace the  numbering in front of it by [Sha07] for
example). The numbering option only offers yes, no, short and bib. I'd like
a "key" option.
How can I achieve that? Any clue, example and/or suggestion is welcome,
Thanks in advance,
