Integer value that controls the Hover Zoom Speed (Figure 1). Value ranges from 5 to 100. Figure 2 shows the light blue transparencies (and darker blue arrows) at the edges of the window and the darker triangular transparencies (arrows) in the corners. Hovering (not clicking) your mouse in any of those blue areas makes the plan scroll quickly in the direction of the arrow. Pressing the keyboard space bar reverses the scrolling direction.
