Hi all,
I don't know if the following scenario usually appears in the workflow
of other Org users as well. Otherwise, I think this patch could be
ignored.
In my workflow I often need to pre- or postpend some LaTeX code
immediately before or after a section. Consider the following example:
------------------
* A section
Lorem ipsum
#+latex: \foo
* Another section
Lorem ipsum
-----------------
The \foo command affects the second section, but for Org it belongs to
the content of the first section. If I comment this section out or mark
it as non-exportable, then the LaTeX code has no effect. I think a
simple solution could be to have the PRESEC AND POSTSEC properties to
prepend or postpend arbitrary code to a section. These properties could be
extended with PRESEC+ and POSTSEC+. An example of use:
* Section
:PROPERTIES:
:presec: \begingroup\foo
:postsec: \endgroup
:END:
...
Best regards,
Juan Manuel

* (org-latex-headline): The `PRESEC' and `POSTSEC' properties prepend
and postpend arbitrary LaTeX code to a section, respectively.
