Thanks for the quick answer and for these hints. In this particular situation (the \subtitle will always be document specific) the latex class is not possible here -- I won't create latex classes per document. An include file just for a subtitle seems overkill. So I went with the macro. If there were multiple offending lines, I'd probably use the include file. Anyway, just for reference, this is the macro: #+begin_src org #+MACRO: subtitle #+latex_header: \subtitle{$1} {{{subtitle(foo)}}} #+end_src Downside is, that \ and , within the subtitle will have to be escaped.
