One of the things I love about Gmail is the ability to use keyboard shortcuts. It really speeds up my email reading/responding because I don’t have to deal with grabbing the mouse as I work through the messages. The one major problem with this was the inability to label messages without the mouse.
I just noticed the fun red link at the top of my Gmail account that means a new feature has been added. You can now use the keyboard shortcuts (l) to label a message. Sweet.
