Vim movement on other programs

Give scrotwm a try. It's a tiling window manager with vim-like bindings by default, written by coders who use vim!

And vimperator for Firefox makes my life much, much easier.

For Bourne-like shells (ksh, bash, ...) try set -o vi to make your command line use vi keys.

Off the top of my head...

• Vimperator for Firefox.
• Awesome, WMII, Xmonad or ion3 window manager.
• Evince supports hjkl.
• vifm filemanager
• there are vi keybindings for readline, which enables them for many terminal apps
• xzgv image viewer

Gmail and several of the other Google apps natively support Vi-like motions.

Also, you might want to try Vimperator and, most definitely, Nethack!
