If the line represents 100%, you can scoot through extra long tracks really quickly by positioning the mark in the line and releaseing the button or something.

Ummm, guys... the FF ramps up to a truly amazing speed already -- it starts out slow, but by the time you are three or four seconds into it, it is FF at the rate of one minute per second -- 60x playing speed. So even a 20 minute track can be gone through start to finish in about 23 seconds. And, if you wanted to be at the 18 minute point of a 20 minute track, you could skip to the next track, and then back into the 18 minute point of the previous one using the REW function.

The REW does not go as fast as the FF, however. (6.5 minute track FF start to finish in 8.7 seconds; REW finish to start in 12.2 seconds. Is this a bug?)
