Add a Trackpoint section next to "Mouse and Touchpad"
Submitted by Matthias Clasen
One setting that people will want to toggle here is ScrollMethod none. Without this setting, the middle button on thinkpads and dells works as a scroll button that switches the trackpoint into scroll mode. This is useful for scrolling in web pages, but it makes middle-click-drag impossible, and some people/apps rely on that input pattern.
Another thing that whot points out as candidate for this section is acceleration - it is a lot more variable for trackpoints than for mice, and will need some ui.
