Here’s how it would work: Start playing a file. While it’s playing push the Bottom button (on the Sansa e200 it’s the one just below the scroll wheel ring thing) to bring up the Music Options menu. Within that options menu one of the choices would be a Jump To… choice. Select that to bring up a dialog in Hour:Minute:Second format. Pressing the left button changes the Hour, the top button changes the Minute, the Right button changes the second. The Center button accepts the current selection. The Bottom button changes direction from forward to reverse and vice versa. Menu/Power button cancels and goes back to the Music Options menu screen.
