Think of it as something similar to an emulated 3rd button, only more complicated. ;) Basicly you define one mouse button using this code in the right InputClass section in /etc/X11/xorg.conf like this --snip-- Option "EmulateWheel" "true" Option "EmulateWheelButton" "8" Option "ZAxisMapping" "4 5 6 7" Option "YAxisMapping" "4 5" Option "XAxisMapping" "6 7" --snip-- If you hold this button (in my case button 8) pressed and move the mouse in a direction, it will not move the mouse pointer but generate corresponding button events. If the mouse is moved a longer distance, more events are generated. Example: Holding button 8 and moving the mouse left will generate several ButtonPressed and ButtonReleased events for button 6, effectively scrolling left. Same for right, up and down. I guess this sounds rather stupid if you are really using a mouse. It's way more useful if you are using a trackball or a trackpoint.
