No it does not and this turns out a problem, also I thought the
ox-beamer code contains a add-to-list which should do add beamer, but it
seems not to do it.

What you say makes send but this seems to defy the whole idea of custom!

Thanks! I will do that and you are very right about custom, it is very
convenient but buggier than I thought.
