This is great. I have made updates to my cheatsheet, I'm now upto v1.3. When I'm completely done I will be sure to post it.

As for Stating things in multiple places, I just feel that it never hurts to have the same thing stated under different actions. Because most of the people using this will go to the group that contain the action they are currently doing, so they may not read other actions. That's why I listed it that way.
