Hi,
When writing a beamer presentation with Org, is it possible to use an
overlay to first produce a list, like
- apples
- beetroots
- cauliflowers
- damsons
- eggs
and then either change the colour of some subset of the items, or put a
tick after each one, e.g.
- apples
- beetroots ✓
- cauliflowers
- damsons ✓
- eggs
?
Cheers,
Loris

Yes, it is possible to use overlays in org beamer export.
Depending on what you want to achieve, there are a number of ways to do
this. One way in to introduce LaTeX directives directly. For instance,
#+begin_src org
1. The first point
2. The second one @@latex:{\only<2->\checkmark}@@
3. the third point
#+end_src
There are also other examples in section 13.8.4 (Beamer specific syntax)
in the info manual.
HTH.

Thanks for the pointer (it's actually section 12.8.4 in my version of
Emacs/Org). I now have
#+LATEX_header: \newcommand{\mytick}{\color{green}{\tiny{(HPC-Kunden)}}}
...
- Physik @@latex:{\only<2->\mytick}@@
- @@latex:{\only<1>{Rechtswissenschaft}}@@ @@latex:{\only<2>{\color{red}{Rechtswissenschaft}}}@@
which does what I want.
I was wondering, however, whether there is a more compact way to do the
second line, i.e. without having to repeat the text for which I want to
change the colour.
Cheers,
Loris

This is really more of a LaTeX question. In any case, I would do
something like this:
#+begin_src org
,#+options: H:1
,* slide
- first
- @@latex:\alert<3->{\only<2->{@@second@@latex:}}@@
#+end_src
You could invert the order of only and alert in that line.
And, if you do this a lot, you might wish to start looking at org macros to make it easier and cleaner/prettier.
HTH,
eric
