I have an IBM ThinkPad style USB keyboard with TrackPoint (similar to the ones Lenovo currently sells). I love this keyboard and would like to use it with a Mac OS X machine I have. Everything seems to work, except that middle clicking doesn't let me scroll. Mac OS X is, however, receiving the middle click from the keyboard because in some programs, like Chrome, it registers the middle click and acts differently. How can I get middle clicking to put me into "scroll-mode" in all programs on the OS?

(I'm aware that some programs, like Firefox, have extensions to support this. I want a more complete solution, though, especially since the main things I do with this computer aren't Web browsing.)

that works, although I wish there were a solution that didn't involve shareware. – G Gordon Worley III Sep 21 '10 at 20:32
After installing you must do some configuration: Choose Settings tab in the configuration window, then choose Middle Button and select action Move To Scroll. – Tarrasch Jun 18 '12 at 9:35
@Tarrasch thanks for the post-installation setup info. Someone recommended controllermate to me for setting this up, but this is definitely a better solution. – user34112 Mar 3 '13 at 23:41
