[beamer &/or latex export] problem with old style footnotes

Carsten,

In latex, I often use a simple \begin{itemize} with labelled items, as in

\begin{itemize}
\item [3] This will be labelled with 3 instead of a bullet
\item [$\checkmark$] This will have a checkmark in lieu of the bullet
\end{itemize}

In org-mode, with beamer mode, I can do this except for the cases
where the replacement text is just a number as org-mode seems to treat
this as a footnote.  I have fninline set in the startup as well as
org-footnote-define-inline set to t globally but the export still
treats these old style footnotes as footnotes.

I saw the following:

http://article.gmane.org/gmane.emacs.orgmode/20073

which seems to indicate you did something to hopefully fix this (I'm
not bothered about the font-lock issue at all, by the way).

I've attached a simple org-mode beamer example.

Thanks,
eric

PS - interestingly, but not annoyingly, "- [$\checkmark$]" doesn't
     work but "- [\checkmark]" does to replace a bullet with a checkmark.

* Introduction
*** The first slide
- The first point
   1. <1-> I would like to say this @emphatically@.
   2. <2-> and this but in *bold*.
   3. <3-> but also this /emphasised/.
- the second point[fn:1: This is a real intended footnote] which has very little to say really but tests out direct labelling of items:
  - [1] The first sub-item
  - [3] The third (although in second place) sub-item
  - [\checkmark] Just to show this works
* The guts of the presentation
*** and more
    :PROPERTIES:
    :BEAMER_extra: 
    :END:
***** this is a short column					      :BMCOL:
which should appear by itself first and afterwards, with a pause, followed by the second column.
      :PROPERTIES:
      :BEAMER_col: 0.2
      :BEAMER_envargs: C[t]
      :END:
      \note[item]{This is a note about this item}
***** <2-> second column 					      :BMCOL:
      :PROPERTIES:
      :BEAMER_col: 0.7
      :END:
      - but this one is much

      - another item

Hmm, this is not an easy thing.  The syntax you are using is entirely
LaTeX specific, so it will fail in other export backends.
Therefore I am hesitating to put this in as a standard feature.

If you want to have this, you could do the following.  It installs
a function into the export process that will protect such item
bullets from further processing.  The regexp looks quite
complex - this is only because there are 5 different
types of bullets and we also must make sure that a level
1 headline will not be mistaken for a plain list item.
What this really does is finding square brackets at
the beginning of an item, and adding a text property to prevent
further processing.

Hope that does what you need.

That makes sense... I have such a latex centric view at times (both
because of lecture preparations and writing academic papers) that I
forget about other export targets!  <blush>

Actually, just yesterday I found that simply adding a space to the
bracketed entry, such as "[ 2]", solves the problem for org-mode and
doesn't affect the latex at all.

Thanks,
