I think it makes a lot of sense to consider that macros can't be used in a
back-end specific way -- the first reason being that you have no way to tell
for which back-end they are written (unlike what we can do with
`org-add-link-type' where we can specify different back-end translations).

OK. I thought I was working on a pure document. Sorry for the noise.

I'll be glad to be your first Beamer tester -- as this is something I use a
lot, even if I do use it in its simple form (no multicolumn parameters, and
the like).

Best regards,
