Super cool VIM Cheatsheet

Vim, actually, gvim.. now that's my editor of choice, lately. I have used emacs before and for some tasks, like editing I18N files I have used EmEditor and Yudit, but for most of my daily work, I have been using vim.This link provides a cheatsheet for some of the vi commands. I find that browsing these cheat sheets every now and then helps, because I cannot possibly train my fingers to use everything the editor has to offer all at once. Every now and then, I think "Hmm.. there's got to be a better way to do this" and either google it (or more recently a9 it) and review some cheatsheets and tutorials to get a better grip on it all. So, do you have any cool vim tips? Or links to cool tutorials?
