My new Magic Mouse rocks for a number of reasons, but I’ve been dissappointed with the two-finger swipe gesturing. It’s used for easily moving through things like iPhoto frame-to-frame. It’s not remarkably complicated: just put two fingers on the mouse and swipe to the left or right. This is straightforward (and awesome) on the trackpad of your standard Mac laptop, but it’s an awkward gesture on a mouse. I can only speak for myself, of course, but I tend to grip the sides of a mouse with thumb and ring finger, leaving index and middle fingers to operate the buttons, or in the case of Magic Mouse: “where the buttons would be if it had buttons and didn’t operate on, apparently, psychic energy.” Gripping the Magic Mouse in this fashion makes comfortable two finger gesturing to the right awkward and gesturing to the left nearly impossible.
The Trick
You need to take your hand off the mouse entirely. Remove your thumb and ring finger grip and let your hand hover over the mouse. Now drop your two fingers lightly back onto the mouse surface and use a very light touch to swipe back and forth. The multi-touch sensitivity is more then adequate to pick up your lighter gesturing, and not gripping the mouse gives your hand the freedom of motion necessary to move left and right with ease.
The best simile I can draw here is that by moving your hand off the mouse you’re basically treating the mouse’s surface like a virtual trackpad. This is an unfamiliar hand posture for people raised on Microsoft mice and corded Apple mice without multi-touch, so it takes some getting used to.
Incidentally, did you know that you can two-finger swipe in Safari to activate the “back” and “forward” buttons? Try it…it’s cool.
