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.

See:
https://github.com/fniessen/org-auctex-key-bindings/blob/master/org-auctex-keys.el
The function org-auckeys-environment I think it does what you want.

you also have "C-c C-v C-d" for src blocks and selecting the language
with completion.
