Hi Jean,

a side question:
................................................................
I installed markdown and Asccidoc in my distro GNU Guix, in order to try 
it out.

...................................................................
but markdown can be used only in installing "ReText" or "ghostwriter"


How do you use them in Emacs?

The same with Asccidoc.

...................................................................
How can I bind that function to some key like C-c a ?

thanks for help

Gottfried
