I have a lot of slides where I want to incrementally show arbitrary
information or code that is *not* part of a bullet list. I've been doing it
like this:

#+BEAMER: \begin{onlyenv}<2->
...some content...
#+BEAMER: \end{onlyenv}

I haven't been able to find any comprehensive org-beamer docs, and I've
been wondering: is there a nicer way to do this using org's beamer support?

I know about the shorthand syntax for bullet lists:

** <1-> Point 1
** <2-> Point 2
** <3-> etc...

But again, this is for content outside of lists.

Thanks,

Not to my knowledge, but I didn't test the new org-e-beamer exporter
for this feature.  Did you?  

I'm unsure your use-case is very common, if it it, hopefully someone 
can implement this in the next exporter.

Best,

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?

That's awesome, I will try this.

Sounds interesting but I'm not totally clear on what "ignoreheading"
environments are for.

Thanks!
