Editing Scrollbar (section)

=== Scroll wheel ===
A scroll wheel on a conventional mouse may also be used. Moving the wheel in a desired direction moves the content in the same direction.<ref>{{cite web|last1=Shu|first1=Andy|title=Scroll bar input device for mouse|url=https://patents.google.com/patent/US6188393|website=Google Patents}}</ref> Most mice contain scroll wheels that only scroll up and down, but some mice contain scroll wheels that allow the user to scroll in any direction (up, down, left or right), including diagonal directions. While scrolling up and down, the direction in which the page scrolls in response to the direction that the user scrolls the scroll wheel can differ depending on the computer's scrolling settings.
