This page was written with VIM, a windows variant of VI. VIM has all the features of VI, but it also includes modern menus, which really help you get started.
Unlike ordinary VI, there's a little indicator in the bottom left corner indicating what mode you're in.
If you're likely to find yourself on UNIX someday, it may be worth it to learn VI or VIM. Besides, if you're running VI on your Windows machine, you're pretty much the definition of a computer nerd.
