"PagewiseScrolling"
• "PagewiseScrolling" is an option for notebooks that determines if a notebook scrolls in steps of one page when the scroll bar is clicked.
• A page is defined as the part of a notebook between two successive page breaks.
• With the setting "PagewiseScrolling" 
True, each click in the scroll bar causes the notebook to scroll up or down to the next page break.
• The default setting is "PagewiseScrolling" False.
"PagewiseDisplay"
• "PagewiseDisplay" is an option for notebooks that determines if the screen display is limited to a single page.
• A page is defined as the part of a notebook between two successive page breaks. With the setting "PagewiseDisplay" True, only a single page is displayed on the screen at a time. If there is any additional space in the notebook window, it is left blank. If the scroll bar is clicked, the contents of the next page are displayed on the screen.
• The default setting is "PagewiseDisplay" False.
"RealTimeScrolling"
• "RealTimeScrolling" is an option for notebooks that determines if a notebook scrolls in real time when you slide the scroll tab along the scroll bar.
• With the default setting "RealTimeScrolling" True, the contents of the notebook scroll in real time as the scroll tab is dragged up or down.
• With the setting "RealTimeScrolling" False, the notebook does not scroll while the scroll tab is being dragged. When the scroll tab is released, the notebook jumps by an amount proportional to the distance that the scroll tab has moved.
"JumpScrolling"
• "JumpScrolling" is an option for notebooks that determines if clicking at a point on the scroll bar causes the scroll tab to jump to that point.
• With the default setting "JumpScrolling" False, clicking at any point on the scroll bar causes the notebook to scroll up or down by a fixed amount.
• With the setting "JumpScrolling" True, each time the scroll bar is clicked, the scroll tab jumps to the position of the pointer and the notebook scrolls by the corresponding amount.
"HorizontalScrollRange"
• "HorizontalScrollRange" is an option for notebooks that determines the maximum distance that the notebook can be scrolled horizontally.
• This option is specified in points (where 72 points equal one inch). The default setting is usually "HorizontalScrollRange" 3024.
"SpeedParameters"
• "SpeedParameters" is an option for notebooks that controls the speed at which scrolling takes place during click-and-drag selection operations.
• The value of this option is a list of four parameters. The first parameter sets the maximum scrolling speed in number of pages per second. The second parameter controls how the scrolling speed responds to the distance that the mouse pointer has been dragged outside the window. The third parameter controls how quickly the scrolling speed approaches the maximum speed. The fourth parameter sets the maximum time in seconds for which scrolling can be interrupted when waiting for cells to be rendered.
• The default setting is "SpeedParameters" {2, 0.1, 1, 0.4}.
