The coarsetracker is a user interface that looks like an ordinary textless button.
The primary function of the coarsetracker is to move positions with the greatest possible extent, thus the name coarse. It moves by the number of pages equal to the DynRadix raised to the power of the TrackLevelMax. This function is invoked by a drag-by-tracker, drag-by-track, or soft-touch operation. The resulting movement always begins with the first line-item of the first page of the chosen group.
The other function is to give the user a visual clue of the position relative to the total number of pages as grouped using the Coarse Granule.
See Scroll Info Tab and Coarse Granule for more information.
