two finger tap (middle click)

view story

http://forums.opensuse.org – In opensuse 11.0 and 11.1 (kde) I was able to tap the touch pad with two fingers to simulate middle-click. It allowed me to use "open link in new tab" feature in firefox with ease. It allowed me to close tabs I no longer needed. The same feature exists in 11.2 (kde4) but requires three fingers to tap. I find this frustrating, and wondered what the steps are to set it back to two fingers. I have no xorg.conf file. (Distributions)
