vimtutor sold me on vim in 10 minutes. o, O, p, P, y, I, A, etc. It was immediately obvious to me how it could be useful, having one-key shortcuts for the most common maneuvers in text editors, even if I were just writing prose.

Next time you're stuck somewhere without internet, as I was, give vimtutor a shot.

Thank you. Just did this and finally understand vim and I have used some weird editors in my day. This really helped to give me an overview
