Whenever I put an empty headline and I add some tag like :B_note: or whatever, the tag end up in the headline.
** Some Frame
*** :B_note:
:PROPERTIES:
:BEAMER_env: note
:END:
[2012-09-03 lun. 09:22]
blah blah
is exported as :
\begin{frame}{Some Frame}
\note{:B\_note:
blah blah}
\end{frame}
I think that the tag should never be used for the headline.
What about you ?
