Hello,

Thank you for your time and effort designing this wonderful plugin.  I would like to request a new feature that would fit more into a key centric work flow:  Mark as read with right arrow and as unread with left arrow.  The idea is that when the user browses through messages, I would easily mark it as read without having to move the mouse into the message (many don't require scrolling).  

Thank you very much!!
Jose Ignacio
