If you use Gmail and Firefox, this could change your life...

[This is for people who are keyboard shortcut junkies. If you like to mouse around, you might want to skip it]

It's a five-step process:

• Install Greasemonkey
  
• Restart Firefox.
  
• Install the gmail-greasemonkey scripts
  
• Reload Gmail
  
• Go to your Gmail window and press 'h' to see what you've got.
  

These scripts were written by the amazing Mihai Parparita. Thanks Mihai!
