The Autoscroll and Scroll Options enables you to define the amount that
scroll during each jump (in either pixels or pages). Autoscroll direction
can be specified as either up or down. The delay interval between each
jump can also be configured. You can prevent the device from automatically
shutting off during an autoscroll; autoscroll will then continue until the
end of the page is reached, the screen is tapped, or the power button is
clicked.
