Well actually all the online editors have awesome scripting capability via javascript:) > - rectangular selection and operations (v: Ctrl-v, e: C-x r ... or rect-mark) Ace (cloud9 editor which friendCode uses) have pretty good support for sublime text style multiple selections, (with ctrl-alt-arrow keys) so emacs or vim style should be easy to implement. The main problem is that there are oly a few people who use online editors, so most of this things are not implemented yet.
