Vimdows Navigation tries to allow you to use Vim (or vim-like) commands outside of vim. The original script was written by Rich Alesi, and most of the credit for this script goes to him. I modified a variety of things, but I would have had no idea how to even begin this if it weren't for Alesi's code.
It isn't perfect, of course, but I've found it useful. You can run the .exe, or download Autohotkey. Either way, this'll run in your system notification area until activated, when it'll show an icon on your taskbar.
Vim "mode": Toggle with Shift+Esc; i will also exit this mode
Quick Vim keys: CapsLock + cmd
Note that because of the way Quick Vim functions, you will have to use Ctrl+CapsLock to toggle CapsLock.
