Wow. You see only what you look for. :embarrassed: > The language is a bit different than your proposal, but the path seems > clear enough to me. Technically the path points to http://orgmode.org/worg/org-contrib/babel/languages/; I'd point it to http://orgmode.org/worg/org-contrib/babel/languages.html as it looks cleaner vs. just looking at the directory of .html files. Either way... the manual totally does it's job and I missed it! Thanks for bearing with me!
