The easiest solution would be to save the text as a "box" in latex and use that box within the headline as the latter would be a simple latex directive that org would have no problem with. I don't have my latex book handy but something along the lines of the following should work: --8<---------------cut here---------------start------------->8--- #+latex: \newsavebox{\complexexpression} #+latex: \sbox{\complexexpression}{\fbox{\fbox{(*\fbox{\fbox{(*\fbox{x()})}[]})}()}} * a headline with \usebox{\letterhead} --8<---------------cut here---------------end--------------->8--- Note that I am not particularly experienced in the use of latex boxes... > or any better way to colorize the text while also > support to export to other target (e.g. html)? No idea, sorry. Maybe others can help here. However, for code blocks *not* in headlines, you could use source code blocks (#+begin_src ... #+end_src) but I'm not sure how they export to other targets. -- : Eric S Fraga (GnuPG: 0xC89193D8FFFCF67D) in Emacs 24.0.50.1 : using Org-mode version 7.5 (release_7.5.274.gd6aba)
