Hi Carsten,

See the line I added manually in the example Org file:

>> #+BEAMER: \frame{\frametitle{Table of Contents}\tableofcontents}

Now, we can discuss about the right title for the TOC slide:
- Table of Contents?
- Table of contents?
- Contents?
- Index?
- Plan?

Maybe that should become a customizable variable with a nice default value...

See the discussion with Eric on

Currently (git version of 10 mins ago), I have nothing defined for `@':

--8<---------------cut here---------------start------------->8---
org-export-latex-emphasis-alist is a variable defined in `org-latex.el'.
Its value is 
(("*" "\\textbf{%s}" nil)
 ("/" "\\emph{%s}" nil)
 ("_" "\\underline{%s}" nil)
 ("+" "\\st{%s}" nil)
 ("=" "\\verb" t)
 ("~" "\\verb" t))
--8<---------------cut here---------------end--------------->8---

Shouldn't `("@" "\\alert{%s}" nil)' be added by default?

That does work. Thanks.

However, couldn't we have that on by default on all nodes? For sure, some
people won't remark some text is cut off in the output beamer presentation,
when the option is not set.

By the way, how are we supposed to add that property in the most easiest
manner?  I never really used column view, but I have troubles when using it

On the node where I want to add that property, I do:
- `C-c C-x C-c' to enter column view
- `right' (arrow) to go in the second column
- `e' to edit the property
... but I'm put in a tag selection menu... What am I doing wrong?

Maybe others have feedback on this. I'm not yet expert either in beamer...

Sure. Thanks -- once again -- for all excellent results achieved so far.
