You can adjust the scrolling speed, and can even opt for a faster scrolling speed when using a modifier key or when “grabbing” near the window’s edge. For example, on my mouse, I tap Option+Command and then click-drag with the primary mouse button.

If you don’t have a multi-button mouse-or if you’ve already used up all of your mouse’s buttons-you can assign this feature to any button with the addition of a keyboard command. If you’ve got a mouse with multiple buttons, you can choose one of those buttons to be your “grab scroll” button just click that button and then drag the contents of the window around. The other new Smart Scroll X feature is called Grab Scroll and lets you “grab” the contents of any window-text, images, a Web page-and scroll by simply moving the mouse cursor around. (You can also temporarily disable the Super Wheel feature by pressing the Caps Lock key.) One glitch I discovered is that the Super Wheel feature doesn’t seem to work in combination with Kensington’s MouseWorks software. A handy related feature is the ability to temporarily increase scrolling speed by holding how the modifier key of your choice.

With this feature enabled, giving your mouse’s scroll wheel a quick spin, or quickly sliding your fingers across your trackpad, will result in a “coasting” scroll it will start out as fast as you would expect, but instead of stopping when you stop (in other words, when you stop spinning the scroll wheel or dragging your fingers across the trackpad), scrolling will continue, gradually slowing down until it “runs out of momentum.” It’s not quite the same as Logitech’s hardware feature, but it’s very similar and works surprisingly well.
