Vim

Vim (Vi Improved) is a flexible and efficient text editor that I always heard about since Mac OS added the X on its name and I started playing with it's UNIX-like features. But some time ago, I found MacVim, which is a very nice port of Vim into the Mac OS X, so I'm now a very happy Vim user.

Since I like to play with my new toys and Vim is highly customizable, I'll put here anything I come up with.

• delimitMate: This is a plug-in that provides automagic balancing of brackets and quotes and it's higly customizable.
• MailApp: This plugin allows Mac OS X users to send e-mails from Vim using the Mail.app application.
