Unfortunately, I can't remember where I read that. I did a quick grep on Calc and Org manuals and didn't find it - but maybe I'm missing something? Or maybe I was just dreaming and Emacs does not have anything like that? Best, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University
