Editing Scrollbar (section)

=== Thumb dragging ===
Dragging the thumb is historically the traditional way of manipulating a scrollbar. By moving the cursor over to the thumb on the screen and then pressing and holding, the thumb can be dragged. This is often done using either a [[trackpad]] or the left click button on a conventional mouse or touchpad. Moving the cursor while pressing down moves the scrollbar's thumb to see different sections of the page.<ref name="BatesPat">{{cite web|last1=Bates|first1=Cary Lee|last2=Day|first2=Paul Reuben|title=User interface component and method of navigating across a boundary coupled to a scroll bar display element|url=https://patents.google.com/patent/US5977972|website=Google Patents}}</ref> On applications native to [[OS X El Capitan|OS X 10.11]] (and some previous OS X versions), scrollbars do not show up on the user interface until the user uses another scrolling technique, such as the two-finger scroll or using the arrow keys. Therefore, the user must scroll using one of these methods first, and then move their cursor over to the thumb, wherever it appears.

On [[Microsoft Windows]], moving the mouse away too far from the thumb while dragging it will reset the scrolling position to prior.
