Re: [O] How to suppress \label commands in beamer export

[Darlan Cavalcante Moreira]

Thanks Eric,

The ideal case if if I could disable label creation and labels would be
created only when I specifically write a <<target>>, for instance. But I
understand this is hard coded right now.

If I don't use overlays at all to change the blocks in the right side and
just put them into separates frames, then the figure in the left (when I
put one there) will slight change its vertical position. This is annoying
and it is the reason why overprint is used.

I'll try to use overlayarea instead. The overlayarea environment requires
two arguments, the width and the height of the area. Overprint is just a
more user friendly way to use overlayarea where the width is "all space
available" and the height is automatically determined as the height of the
largest thing inside the overlayarea.

Since overlayarea requires two arguments, like
--8<---------------cut here---------------start------------->8---
\begin{overlayarea}{width}{height}
\only<1> {lalala}
\only<2> {lelele}
\end{overlayarea}
--8<---------------cut here---------------end--------------->8---
is there a suggested way to map oberlayarea into
org-beamer-environments-extra? The only way I can think is to require the
user to type "{width}{height}" in the headline (with the curly brackets)
and use somethink like "\\begin{overprint}%h" in the template definition.
