Texteditor Demo - VI/VIM (Tim Gremalm)

Addicted To vi (http://www.gnu.org/fun/jokes/vi.song.html)

You press the keys with no effect,Your mode is not correct.The screen blurs, your fingers shake;You forgot to press escape.Can't insert, can't delete,Cursor keys won't repeat.You try to quit, but can't leave,An extra "bang" is all you need.
