adds Click and drag support to scroll the page. It is a free Google Chrome Extension.
This extension makes it possible to to scroll pages as if the scrollbar was right under your pointer. Just press the right mouse button (or any other of your choice) and move the mouse.
The extension is based on the Wet Banana extension and inspired by Scrollbar Anywhere for Firefox.
If your mouse lacks for a scrollwheel or you simply want the ability to click anywhere in the Chrome browsing pane and begin scrolling, Scrollbar Anywhere adds in mouse-based scrolling that isn’t dependent on clicking the scrollbar or using a scrollwheel.
