The "Page" slider is used to control which of the other sliders are shown at any given time, because the screen would be cluttered if all the sliders were displayed at the same time. The "Outline?" slider is used to make the outline around Mario/whoever appear and/or disappear. The other sliders do about what you'd expect.
