Hi,
Is it possible to suppress the \label{sec-1} lines following each
headline after a LaTeX export? I've found no mention of this in the
manual, and the presence of headline labels is breaking my Beamer TOC.
Thanks -- Eric

I don't think so: they seem to be inextricably bound with headings. The
code in org-latex.el says:
(let* (...
(label (org-get-text-property-any 0 'target heading))
...)
and then
...
(when label
(insert (mapconcat (lambda (l) (format "\\label{%s}" l))
label-list "\n") "\n"))
...
I recall having problems with labels (among other things) in combination
with beamer before (I "solved" the problem by running the tex file
through a script to just get rid of them), but I don't remember what the
problem was. Maybe it's time to go back and look at the thing again.

PS. Here is a quick-n-dirty patch to disable them - ymmv, uayor and several
other cya disclaimers :-)

Hi Nick,
Thanks for the patch, sadly I rely on labels in my other latex exports.
For now I'm just using the following little elisp function.
--8<---------------cut here---------------start------------->8---
(defun schulte/clean-beamer ()
"remove the \label{sec} headers from latex Beamer documents
that have been exported by org."
(interactive)
(save-excursion
(goto-char (point-min))
(while (re-search-forward "^\\\\label{" nil t)
(move-beginning-of-line nil)
(delete-region (point) (save-excursion (forward-line 1) (point))))))
--8<---------------cut here---------------end--------------->8---
Thanks -- Eric

Hi Eric,
if you make the function first search for \documentclass{beamer}, then
you
could add it to `org-export-latex-final-hook'.
