[O] shorcut for #+BEGIN_xxx ... #+END_xxx

[Joseph Vidal-Rosset]

Hello the list,

I am sorry to ask a so elementary question but I would be happy to get a
mean to have, like with CDlatex or like in LaTeX a shortcut to get

#+BEGIN_my_choice_of_environment


#+END_my_choice_of_environment

I know that there is  <s  TAB for source , <l TAB for latex and so on, but
it would maybe be useful to choice the environment, like with C-e in LateX
+ auctex, or like with C {  with CD latex.

Help and suggestions are welcome.

Best wishes

Jo.
