It’s a feature that I rolled my eyes at when I got my mouse, but now use several times a day. Unlock the wheel and spiiiiiiiiiiiiiin until I get far enough down the page. So much more convenient and versatile than clicking and dragging the scroll bar tab.
On Firefox I use ScrollAnywhere extension which I configure to use right-down drag to scroll large amounts with little movement. Helps tremendously with lengthy pages and I miss being able to use it in code editors.
