Undo in vi - vi cheat sheet

[Pan]

Everytime I forget a vi function I have to go search the web and waste time to find it. This time it was how to undo.

Does anyone have a good vi cheat sheet for me that I can print out and carry arround?

BTW: Undo is just a "u" (without quotes).

I've got a cheat-sheet hung on my wall and I have "The Mug of VI" which is a coffee cup with vi cheat-sheet printed on it. My boss gave me the cheat-sheet I have on my wall.
