You can look a bit back up the list for the discussion. I'm using two
files, I think:
noweb.ts stored in ~/.TeXmacs/styles, and a few key bindings in
~/.TeXmacs/progs/my-init-texmacs.scm

I installed noweb, and maybe that's it. Attached is a sample TeXmacs file.

Tell me if it worked...

noweb.ts:

The key bindings: in ~/.TeXmacs/progs/my-init-texmacs.scm:
--
(kbd-map
("C-1" (make 'noweb-ref))
("C-2" (make 'noweb-fragment))
("C-9" (choose-file (texmacs-save-buffer "verbatim") "save
verbatim file" "verbatim") )
)
