Nope, you have no clue :) thats what a trackpad is good for. The trackpad is easily reachable with your thumb without leaving your fingers too much from the keyboard (most linux distros have the right of the trackpad configured as scroll area). So no annoying multi finger scrolling needed.
Furthermore, middle mouse button + trackpoint scrolls as well, so scrolling really isn't an issue.
