Is it possible to enable autoscroll (scrolling on mouse wheel press) in mac os? In windows it works out of the box, in mac id does not. Macos 10.6.8, Chrome v21
There's an extension called AutoScroll that enables scrolling while pressing a middle button.
Smooze offers that, among other things. (I'm the developer)
What differentiate it from other cross platform suggestions is the ability to use it in every mac app while still identify links, for example. (in case you use your middle button drag to grab and throw but still want that a middle button click will act as a middle button)
Also, upon releasing the Auto Scroll, the scroll will continue to animate just like the iPhone scroll works. (this of course can be configured or turned off)
