What is this group? Well simply put..
When you push the following keys it will change your clan tag to the text:

W: I'm Running!
A: Moving Left!
S: Moving Back!
D: MovingRight!
Shift: I'm Walking!
Ctrl: I'm Ducking!
Space: I'm Jumping!
Mouse1: I'm Firing!
Mouse2: I'm Aiming!

And all of the keys will still have normal function!

So now...
