I don’t like when my touchpad clicks because of tapping. With MaxTapTime I could disable this function. When I surf the net with Firefox and touched the lower area on the touchpad Firefox goes back/forward, this could be disabled with HorizScrollDelta . Look in your /etc/X11/xorg.conf file :
Section “InputDevice”
Driver “synaptics”
Identifier “Mouse[1]“
Option “Buttons” “5″
Option “Device” “/dev/input/mice”
Option “Emulate3Buttons” “on”
Option “InputFashion” “Mouse”
Option “Name” “Synaptics;Touchpad”
Option “Protocol” “explorerps/2″
Option “SHMConfig” “on”
Option “Vendor” “Sysp”
Option “MaxTapTime” “0″
Option “HorizScrollDelta” “0″
Option “ZAxisMapping” “4 5″
