Many thanks Nicolas. I like Fabrice Niessen's work and I'm using
leuven-theme, it is in my opinion very efficient to work with org-mode.
So I have tried immediately this org-acutex-keys-el.
But as I had a message error referring to the variable
org-structure-template-alist ,  I have succeeded to customize this variable
as I want, and in fact I do not need org-acutex-keys-el , all works
perfectly with <key  TAB, and I keep Cc-Ce to export, as usual with
org-mode.
But again, thanks , to you and to Rasmus.

Jo.
