If you hold down the right shift key while pressing the right button, it interpretes that as a middle button press. I'm not completely certain, but I seem to remember it has to be the right shift key and not the left. The one machine where I use that is a laptop and I've gotten into the habit of holding the shift key with my pinky and hitting the right button below the touchpad with my thumb. Still not as nice as a real middle button, but it serves in a pinch. BLS
