For Gmail Users… Keyboard Shortcut Guide!
March 12th, 2009 by David Safar
As far as I know, this isn’t new, but I just discovered it, and it’s exactly what I’ve wanted for some time now.
To see a guide to Gmail’s keyboard shortcuts, just type a question mark when focus is not in a text-entry field.
Never knew that was there, but always wanted to see it! 
Many thanks to LifeHacker for this one.
