It is supposed to report button 8 presses to the X clients - what the clients
do on those is up to the client, toolkit & window manager, and is configurable
in many of them.
There's a defacto standard that buttons ids 1 2 3 are the main mouse buttons
(primary as 1, either leftmost or rightmost depending on whether you use your
mouse right-handed or left-handed, secondary as 3, and the "middle" one as 2),
ids 4 & 5 are vertical scroll wheel events, and 6 & 7 are horizontal scroll
wheel events - all others are just more buttons with no specific role assigned.
Even what the scroll wheel does is up to the application - it can scroll your
text area, zoom in and out on an image, go forward/back in a browser or
perform some other application-specific function.
