When there are many tracks, how fast can the BROWSE display section be scrolled?

The rotary selector has an acceleration mode function. When turned slowly, one track is displayed at a time. When turned quickly, tracks are skipped while scrolling. The number of tracks skipped depends on the speed at which the rotating section is turned. When the rotary selector is pressed for several seconds, the jump mode is set, allowing several thousands of files to be browsed quickly.
