beamer columns and printout

beamer columns and printout

Hi,

I'm interested in using org-mode to generate beamer slides and an
article-like printout (using the article class, usepackage{beamerarticle}
and latex export) from the same source, and I am running into two problems
with the export to article when there are multiple columns.

1.) I often use an empty headline with B_columns tag to allow me to specify
top alignment. E.g.,

#+begin_src org
*                                                             :B_columns:
:PROPERTIES:
:BEAMER_env: columns
:BEAMER_opt: T
:END:
** Column 1                                                     :BMCOL:
:PROPERTIES:
:BEAMER_col: 0.35
:END:
** Column 2                                                :BMCOL:
:PROPERTIES:
:BEAMER_COL: 0.6
:END:
#+end_src org

In the printout, this yields an ugly empty section with a number if num:t.
Is there a better way to pass [T] to the title-less columns environment, or
(less preferably) a way to specify a title for the section without it
appearing on the beamer slide?

2.) In the above example, the B_columns and BMCOL tags get exported to the
latex file for the printout (with an error because the underscore is used
outside of math mode). Can these be suppressed?

Thanks,
  Seb

I've solved the first problem, using a something similar to what has been
suggested here:
http://stackoverflow.com/questions/10295177/is-there-an-equivalent-of-org-modes-b-ignoreheading-for-non-beamer-documents

The solution is to define
#+begin_src emacs-lisp
(defun sf-ignore-headline (contents backend info)
  "Ignore headlines with tags `ignoreheading" or `columns'."
  (when (and (org-export-derived-backend-p backend 'latex 'html 'ascii)
             (string-match "\\`.*\\(ignoreheading\\|columns\\).*\n"
                           (downcase contents)))
    (replace-match "" nil nil contents)))

(add-to-list 'org-export-filter-headline-functions 'sf-ignore-headline)
#+end_src emacs-lisp

This removes headlines with tags "columns" (or "ignoreheading", for that
matter), which is what I wanted. Any ideas for the second problem? I.e.,
how to get rid of the BMCOL in export to latex/html/etc. while keeping the
headlines/content?
