Interesting. What about providing an "againframe" environment (on par
with "appendix", "note", etc.)?
It would use "BEAMER_act" property to set the overlay specification, and
a "BEAMER_ref" property using link syntax to refer to a particular
section. Here's an example:
--8<---cut here---start->8---
* section
** My frame title :B_frame:
:PROPERTIES:
:BEAMER_env: frame
:END:
Some text. Some text. Some text. Some text.
Some text. Some text. Some text. Some text.
** section :B_againframe:
:PROPERTIES:
:BEAMER_env: againframe
:BEAMER_act: 2
:BEAMER_ref: *My frame title
:END:
This section will create "\againframe<2>{sec-1-2}".
** Following frame
etc.
--8<---cut here---end--->8---
This is not really cleaner than your workaround, but at least, it feels
more integrated. Another advantage is that you don't need to know the
label of the frame being resumed.
For convenience, when asking for an "againframe",
`org-e-beamer-select-environment' would always ask for "act" and "ref"
properties, since those are mandatory anyway.
I don't mind implementing this, but I'm not sure it's worth the
(although limited) hassle.

Well, thanks for this It solves an easy case that has already asked for in
the past.
Now I can do :
* section
** My frame title :B_frame:
:PROPERTIES:
:BEAMER_opt: label=tcs
:BEAMER_env: frame
:END:
Some text. Some text. Some text. Some text.
Some text. Some text. Some text. Some text.
* section :B_ignoreheading:
#+BEAMER: \againframe<2>{tcs}
** Following frame
etc.
Not as clean as we might want it, but it is working ok. I had to add an
"invisible" section
else the againframe is not exported between frames, but inside the
preceding frame.
I don't think it was possible before.
I think it may prove useful to be able to chose the label for the frame.

You refer to these labels when you create an internal link (fuzzy, by
custom-id, or by id) to the headline. So the idea is that you don't have
to bother with label's name.
Unfortunately, there's one limitation for now: it isn't possible to
specify an overlay for the target. For example:
--8<---cut here---start->8---
#+OPTIONS: H:1
* Frame 1
:PROPERTIES:
:CUSTOM_ID: frame1
:END:
#+ATTR_BEAMER: :overlay "+-"
- item 1
- item 2
* Frame 2
[[*Frame 1][Link to first frame]] (1)
[[#frame1][@@e-beamer:<2>@@Link to first frame]] (2)
--8<---cut here---end--->8---
(1) will produce \hyperlink{sec-1}{Link to first frame}
(2) will produce \hyperlink<2>{sec-1}{Link to first frame} (*)
At the moment, there's no way to produce:
\hyperlink{sec-1<2>}{Link to first frame, second overlay} (+)
I may swap the export-snippet usage in second case, if (*) is less
useful than (+).
Note that I hardly, if ever, use links in my presentations so
`org-e-beamer-link' is probably sub-optimal.

Considering the remark above, I'm don't think that's the best way to
handle the problem. On the other hand, "label" is an option and should
be treated as such (that is, an user should be able to provide its own
value for it). It is implemented now.

[O] Labels in beamer new exporter
Hi all, I'm trying to reference a slide using the beamer new exporter. Each frame gets its own label automagically (sec-#-##). Is there a way to reference those labels later on ? Using emacs-lisp ? Or ? I tried another way to solve my problem and wanted to define my own label on a frame : ** My frame titles :B_frame: :PROPERTIES: :BEAMER_opt: label=tcs :BEAMER_env: frame :END: Unfortunately, the new latex/beamer exporter does not seem to check that the user may have wanted to put his/her own label on a frame and it adds its own label to the user defined one. It is not that difficult to patch org-e-beamer--format-frame to avoid adding label when the user provides its own, but is it the right thing to do ? Greetings, -- Fabrice
