There are already a number of extensions for Chrome, which can add the "scroll to the top" button in all possible places. With TopScroll you even don't need to aim any buttons, moving a mouse cursor to the screen left edge is much easier and faster.
Also, after scrolling to the top you can return to previous position on the page just by clicking on the edge one more time.
