Trackball Scroller Chrome 插件, crx 扩展下载

                    
Scroll with your trackball
Trackball Scroller lets you scroll pages with your trackball. When you activate "scroll mode", you can roll your trackball to scroll. Browse infinite-scrollable websites or long documents easily.

Flick the ball to jump quickly, or move it slowly to scroll in a smooth continuous manner; gives better scrolling experience if you're not satisfied with your trackball's scroll wheel. 

No spyware, no ads, no sending user data anywhere.

NOTE: DOESN'T WORK on most pages on Yahoo using sandboxed iframe - Yahoo News, Finance, etc.

Works best with trackballs, feels awkward with traditional mice, no big changes with two-finger scroll on touchpads - except one finger vs two fingers.
