Hi,

I use the attached code to "highlight" (using the command of this
name) a code sample in Emacs and copy it to TeXmacs. Most of the work
is done in Emacs since I studied Emacs more (long, long ago) and it is
better at self documenting. I struggled to find a way to put comments
side-by-side, or over code, finally I stumbled upon "tab" -- I hadn't
realized its power. Each line of the inserted code has place to
provide plain-text comments. Since it is for slides and I have bigger
than standard magnification for them, I paste the code inside \tiny or
\very-small, so the \small size of comments is really bigger than the
code.

Perhaps someone can provide me with code that combines "Edit / Clear"
(bound to M-g) and "Edit / Paste from / LaTeX" and binds it to a key?
(For example, code to put into "my-init-texmacs.scm".) Here's my
emacs-side binding:

;; Copy a highlighted in latex code sample to clipboard.
(load-file (concat system-home-path "Emacs/prepare-highlight.el"))
(global-set-key (kbd "C-c w") 'latex-highlight-code-region)

Cheers!
