Thinkpad Scroll Daemon

tp-scroll allows the use of the middle mouse button on a Trackpoint keyboard for scrolling up and down in applications that support the use of the wheel on an Intellimouse. The scrolling action is essentially the same as is used on the Trackpoint Windows drivers. It also provides an exponential acceleration feature, which provides smooth cursor acceleration as pressure on the stick increases. tp-scroll is designed for use on three-button IBM trackpoints, but is compatible with any mouse-like device that uses the 3-button PS/2 protocol. It is not related to, but is compatible with, the Trackpoint hardware control daemon tp4d.
