Thanks, I will give Eric’s suggestion a go.

The only snag is that on export I get \response\{BLAH BLAH\} Easiest solution is @@latex:\response{blah blah}@@ but that will lose you all the org formatting. Longer solution is to use environments, such as #+begin_response blah blah blah #+end_response and define a "response" LaTeX environment, along these lines: #+latex_header: \makeatletter\newenvironment{response}{\textcolor{red}}{}\makeatother (untested) Notice also that commands and environments in LaTeX are not interchangeable; there are things only commands can do and things only environments can do. (Well, not really - technically, I guess, environments are strictly more powerful than commands, though I'm not 100% sure - but some things are quite difficult to do with environments and trivial with commands.)
