Vim normal mode emulation anywhere in Windows, powered by Autohotkey.
Vimdows-ng allows you to use Vim (or vim-like) normal mode anywhere in Windows.
Use the provided executable or the .ahk script with Autohotkey. It does not require any special permissions and will run in your system notification area until activated, when it'll show an icon on your taskbar and a small tooltip overlay in the top-left corner of the screen.
This is based on previous work of achalddave who himself modified the original script by Rich Alesi, and most of the credit for this script goes to him.
If you are not familiar with VIM yet, you might want to try a vim tutorial. Or you might want to try Vim Adventures :)
A good in-depth book is Practical VIM.
