I have become more addictive using gmail these days specially because we have to reply to users who send their computer problems on TroubleFixers
While handling these large number of email, I was just trying to get to know quick and easy to remember shortcuts for gmail. So, I google for gmail keyboard shotcuts and got landed to a page here
But after seeing these shortcuts I was even worried how could any one remember all of them, I filtered out some easy to remember shortcuts.
