I’ve been giving preference to a keyboard over mouse since I discovered vim for myself, as it’s a faster and more convenient way to go. I am a Chrome user and recently I found an amazing plugin: Vimium.
It does exactly what the name suggests, allowing you to use vim-like commands in your browser. You can freely move, switch between tabs, work with forms and click links using familiar vim key bindings.
A two minute long introductory video explains basic commands and you’re all set! I’ve been using Vimium for over a week now, an amusing experience which allows you to throw your mouse in a dark corner (well, not exactly: Vimium still has some issues with over-bloated ajax pages, not to mention Flash and other nasty stuff).
