Cheat sheets for Maya!
Well its not really cheating, but these are very useful sheets to print and keep handy when working within Maya. If your like me and tend to forget the vast amount of keyboard shortcuts available across a wide range of creative software, these can be extremely useful and quick to refer to if you have them sitting close at hand.
I would recommend these links...
Shortcutmania.com: Maya Keyboard Shortcuts. (printable version).
DigitalArtsGuild.com: Maya Cheat Sheet. (pdf. version).
