The LineSize property gets or sets the size of the interval when moving the slider with the keyboard or mouse wheel. The PageSize property gets or sets the interval for moving the slider with for page-related keys or mouse wheel. These properties affect the feel and operation of the Slider. Use a small value of LineSize to allow fine adjustment of the slider via the arrow keys. Use a large value of PageSize to allow quick changes of Slider position using the Page Up and Page Down keys, or by clicking to either side of the Slider pointer. Use Home and End to move quickly to the MinRange and MaxRange values via the keyboard, independent of the PageSize setting.
