One option would be to turn all those notes into footnotes

I'd really be interested to get more input on this issue.

Maybe it is better to simple ignore notes when exporting to other formats.

For me notes in beamer are useful only to give me an idea of what I intend to talk about in the presentation and help me training for the presentation. They are not really "part of the final exported document" and sometimes I put a lot
of information in them (possible in a different language from the

Also, the contents in notes can be anything such as a table or a figure. This
obviously would result in an error if or if org tried to put them into a
footnote when exporting to other formats.

Therefore, the question is has anyone here any interest in notes when exporting
to other formats or do they only make sense when exporting to beamer?

My case is similar.  I teach a class each week and, so far, have created
two documents; a set of handouts and my notes for teaching.  Generally
these documents start from the same original and I modify and expand the
notes I use for teaching while leaving the handouts a smaller doc for
those in the class to take their own notes from.

I don't use beamer as the handouts tend to be 6-8 pages of 'normal' text
as it is and my teaching notes are usually far larger.  I don't want to
manipulate a stack of paper while teaching.

For me, notes are rather important: in addition to reminding me what to
say, they are essentially a second level to the presentation (and I
always include them in any handouts). Somebody who has a vague interest
in the subject can look at the slides. If they want to go into it a bit
deeper, they can look at the notes.

My case is similar but I don't 'expose' my teaching notes to the
students for a variety of reasons.

So unless somebody comes up with a really good idea, delaying any
org-specific implementation might be the best way forward: it would save
wear-and-tear on Carsten, allow the rest of us to catch up and gather
some experience and perhaps come up with better ideas on how to handle

I guess my request is similar to what has been discussed above in that I
would *very* much like to maintain handouts and teaching material in the
same file and then export it to two different files as necessary.  This
would make my job a lot easier to manage.  I could decide which tables,
figures, text, etc are common to both docs and which are just for me and
everything happens automatically behind the scenes.

Beamer output is not critical for me (or even necessarily desired) right
now but I would like a way of marking some text for 'limited' export.
Using a special notation is not a problem if it gives me the ability to
maintain a single document that I can export to two different LaTeX/PDF


I use Org-babel to accomplish this. Its literate programming facility lets you define a block of text and re-use it wherever you like. You can "tangle" as many .tex files as you want from a single Org-mode document.

You can find some examples here:


I had been avoiding the literate programming aspects of org-babel since
my previous experience with literate programming was less than
satisfying.  However, this use may be just what the doctor ordered.
I will have to give it a look.
