I now understand your intention! Make that old joke become true: "Emacs is a great OS, it's just missing a good editor" :-D ..... Nachtigall ick hör dir trappsen ... Seriously: There's not that much code to write in the language files. The features seem more than worth it. I just had little snippets in mind... hrm, sorry. > Footnotes: > [1] http://orgmode.org/worg/org-contrib/babel/org-babel.php#results > > [2] http://orgmode.org/worg/org-contrib/babel/org-babel.php#languages OK - not _really_ RTFM :-D I remember I stared at those sections last night - seems I was half asleep already.
