new Gmail functionality??!! (email preview)

I accidentally middle-clicked on a gmail message, and got some crazy new message preview!

Try it out!

 

I have another action on middle-click

 

I just get the same "scroll" button that pops up...


Can you take a screenshot and post?..

 

Never mind, I just found out it's because of my 'Better Gmail' Firefox addon

It's awesome though, here's the screenshot

 

Where did you got that addon ? Can you elaborate the functionality ?

It's one of the best plugins I have! I blogged about what else it can do, but basically you can middle click to preview the mail without opening. It saves time

Okay, I'm a newbie...I've never heard of the term "middle click". What exactly is that?

 

Clicking the middle mouse button
