MacVim

Vim is one of the best advanced text editors around, whose origins lie in a similar app on UNIX systems called Vi.

Mac users can already use Vim thanks to MacVim, another version of the programme adapted to Mac OS X operative systems.

The best additions to MacVim are the tab system, transparencies, full screen editing and a very complete toolbar with lots of features: save and import sessions, run Vim scripts, multibyte editing and so on.
