TrackPoint

IBM TrackPoint The TrackPoint is IBMs name for the stick that sits between the g, h and b keys of the keyboard. It is used as a pointing device and hence as an alternative to an external mouse or a touchpad. What sets it apart from devices found in notebooks of other manufacturers is that it has no moving parts. It works using a solid state strain gauge. Its tap-to-click feature, which means that you can tap the stick to do a left click instead of using the left mouse button, is also handy.
