Adds the OnTab keyword for the keys file

Adding the following lines to the keys file restore the old behaviour to
use Mouse2 on tabs to start tabbing, and keep OnTitlebar Mouse2 to lower
the window.

OnTab Mouse2 :StartTabbing
OnTab Move1 :StartMoving

Note: Internal tabs are triggering both OnTab and OnTitlebar events.
