Well I have no problem trying to understand scheme and trying some
hacks. I have downloaded "Teach Your Self Scheme in Fixnum days",
"Structure and Interpretation of Computer Programs" (sicp) and "How to
Desing Programs" (htdp) for teaching myself scheme. In fact I think that
from a learning perspective, the last one (htdp) is better, which makes
me think another question: How can I change the Scheme interpreter of
TeXmacs from Guile to mzscheme (the used in htdp for examples?)

I can give a try. But I know almost nothing about scheme, I think from
my ignorance that actions links is the way to go. Just show me the path
to the source (code), Obi-wan-Allouche, ;-) and where to start, and I
will give my best.
