I've recently moved into an office that has standardized on Apple computers and have run into something that I have used with Linux that I know is going to drive me nuts on the Mac. I use a Logitech MarbleMouse, a trackball that does not have a mouse wheel. On Linux, there is a configuration option (EmulateWheel and EmulateWheelButton in evdev) that let's you press a button and have mouse/trackball motion act like a scroll wheel. Is there anything equivalent on Mac?
