Hi Jean,
I installed markdown-mode in Emacs, but I have Emacs 28.2, so I can’t 
set the keymap for C-c a.

I also installed Pandoc and emacs-pandoc-mode

I opended emacs and evoked markdown-mode and it opened my file in 
markdown-mode. So at least it works.

So now there is only the question how to use it.

Kind regards

Gottfried
