Re: [O] beamer columns and printout

I've solved the first problem, using a something similar to what has been suggested here:

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?

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:
:BEAMER_env: columns
:BEAMER_opt: T
** Column 1                                                     :BMCOL:
:BEAMER_col: 0.35
** Column 2                                                :BMCOL:
#+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?
