Hi there.
I'm trying to use the \only<> command to produce a beamer
presentation but it seems that org-beamer filters out this. I've
tried it in many different ways, and didn't get the desired effect.
Particularly, I've tried the obviously wrong thing:
#+STARTUP: beamer
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [smaller, presentation]
* Foo
** Slide 1
\only<1> {
*** Block1 :B_block:
:PROPERTIES:
:BEAMER_env: block
:END:
- bla11
- bla12
- bla13
}
\only<2>{
*** Block2 :B_block:
:PROPERTIES:
:BEAMER_env: block
:END:
- bla21
- bla22
- bla23
}
Which obviously break-up. And I also tried what I believe would be a
nice syntax for this:
* Foo
** Slide 1
*** Block1 :B_block:
:PROPERTIES:
:BEAMER_envargs: \only<1>
:BEAMER_env: block
:END:
- bla11
- bla12
- bla13
*** Block2 :B_block:
:PROPERTIES:
:BEAMER_envargs: \only<2>
:BEAMER_env: block
:END:
- bla21
- bla22
- bla23
Apparently the parser just removes the "\only" and interprets this
as <1> and <2>. The resulting latex is exactly the same as if the
"\only" wasn't there.
Is there a way to use the "\only<>" overlay in a clean way?
What does \only do?
