Using new back-end (and probably the old one, /mutatis mutandis/), you
can use something like:

  (add-to-list 'org-e-beamer-environments-extra
               '("onlyenv" "O" "\\begin{onlyenv}%a" "\\end{onlyenv}"))

You can then add an headline above your information and set its
properties "BEAMER_env" and "BEAMER_act" to, respectively, "onlyenv" and
"2-". You can set easily the first one with C-c C-b when
`org-e-beamer-mode' is active.


I am thinking about providing this feature with "ignoreheading"
environments. I.e.,

--8<---------------cut here---------------start------------->8---
* Text                                           B_ignoreheading:
  :PROPERTIES:
  :BEAMER_env: ignoreheading
  :BEAMER_act: 2-
  :END:

  contents
--8<---------------cut here---------------end--------------->8---

would provide

\begin<2->{onlyenv}
contents
\end{onlyenv}

Though, I'm not sure about which environment to use in this case:
"onlyenv", "visibleenv", another one. Any comment about this?


Regards,
