I've been using BEAMER_env: ignoreheading to generate columns of
bulleted lists as follows
#+begin_src org
* hidden heading 1 :BMCOL:B_ignoreheading:
:PROPERTIES:
:BEAMER_col: 0.5
:BEAMER_env: ignoreheading
:BEAMER_envargs: [<+->]
:END:
** Item 1
** Item 2
* hidden heading 2 :BMCOL:B_ignoreheading:
:PROPERTIES:
:BEAMER_col: 0.5
:BEAMER_env: ignoreheading
:BEAMER_envargs: [<+->]
:END:
** Item 3
** Item 4
#+begin_src org
But the "[<+->]" is not included in the LaTeX export so the bullets
are not revealed sequentially. Is there a way to include this flag in
the export? Thanks,
Derek Thomas

To answer your explicit question, you need to specify either "c" or "C"
for a column envargs setting, as in "c[<+->]" or "C[<+->]", the
difference being that with lower case c, the argument applies to the
column and with upper case C, it applies to the columns environment.
You need one of these to get the export to work.
Having said this, I have no idea how to get beam to do automatic
column overlays, as you seem to want. I have always had to use <1->
etc. So I would have envargs for the first column set to "c<1->" (note,
no square brackets) and "c<2->" for the second.
HTH,
eric

It seems that with the options you suggested, the "[<+->]" argument is
passed to the \columns environment instead of the \itemize environment
within the column. Beamer doesn't accept this argument for the
columns environment. Is there a way to pass the argument to \itemize?
Thanks,
Derek

Sorry for the confusion. I thought you were trying to specify those
arguments for the columns as I misread your original query.
For lists, you can specify individual item overlay specifications, such
as:
#+begin_src org
The following is a very convoluted list of items:
- <1-2> one item
- <2> another
- <3-> and another
- <1-> etc.
#+end_src
but I don't know how to pass anything to the =\begin{itemize}=
directive. Sorry. Maybe somebody else (Carsten, Nicolas) can help?
I've never found a need for automatic overlay specifications such as
<+-> for presentations, partly because I'm against too much hiding and
incremental revealing of text on slides, unless for a very specific
pedagogical purpose (but this is very much a personal bias).
