Hi Maxim,

Thanks for replying.

To answer your first question, no, if I type anything after 
the "?", it doesn't work. Texmacs seems to be stuck.

I read the post you reference in the Texmacs users mailing 
list. I think Joris' suggestion is to use the "cond" 
statement to condense the sequence of "when"s.  I don't know 
much about Scheme programming either, but I could give it a 
try.  But I don't know exactly what the "when" statement 
does. It is not in the Scheme manuals I've looked at, and it 
is not in Guile either.

                                        Kostas
