By default, the middle button on my Thinkpad’s Trackpoint is set to a proprietary scroll mode. This proprietary scroll mode doesn’t work in many applications (although sometimes changing config files can fix that), but the real problem is that I need the Trackpoint to act like a three button mouse.
For example, in CoCreate PE, I need all three buttons to easily manipulate the model: Ctrl+Right mouse button pans, Ctrl+Left zooms, and Ctrl+Middle rotates.
At least in Windows Vista, the Trackpoint configuration page is not a model of clarity, but after some googling and playing around, I’ve found two configurations that make the center Trackpoint button work like the middle button of a 3-button mouse.
The TrackPoint setup is a page on the Mouse Control Panel applet.
