IBM TrackPoint – TP4EX.EXE
TP4ex.exe installs with the IBM TrackPoint input device. The trackpoint replaces a mouse with a small touchpad. You navigate by moving your finger across the pad. Tapping the pad with your finger is similar to clicking a mouse button, it will select something. This file adds accessibility options such as 'stickykeys' to your TrackPoint. If you use these, leave the file in place. If not, you can remove it.
