But yes, this is in fact ambiguous since org parses out from point to see if it is inside a latex fragment. So you need to put point to the right place in this case. Or, to be on the safe side, do the whole subtree with `C-u C-c C-x C-l'. - Carsten > > Thanks > > > > 2009/8/11 Carsten Dominik > > On Aug 11, 2009, at 3:41 PM, Nick Dokos wrote: > > waterloo wrote: > > Excuse me . > I put the following latex code in an org file , and put point in > it ,C-c > C-x C-l.
