Vim
Vim is an extremely configurable text editor designed to enable fast and efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems and now days it even ships with Mac OS X. I use Vim every day for tasks like programming, writing emails or just editing config files. Since i spend a lot of time using Vim I have invested some time in learning how to use it as efficient as possible.
If you are a Vim user, check out my Vim configuration page and my .vimrc, customized during a decade =)
If you still haven’t been enlightened and need some motivation to change the Vim editor. A good way to start is to watch when the author of Vim, Bram Moolenaar visits google techtalk and talks about efficient editing
