Swapping mouse buttons in x86config-4

I am accustomed to my middle mouse button being my context menu
and my right button being my scroll button.
In knoppix it is opposite of that and I would like to change it.
What option would I use to do that?
Possibly Option "SwapMouseButton" "2-3"

Anybody know if it's possible?
