Gestures have become an important form of interacting with your Mac, ever since Apple introduced multitouch for the trackpad. It started with a simple collection of two finger gestures – spread and pinch to zoom in and out, secondary click and two finger pan – as well as redefining a few single touch gestures. Of course, as time passed they crammed in room for more fingers. We’ll not go that deep into it. Mavericks doesn’t really differ that much from Mountain Lion in terms of gestures. The real updates have happened to the interpretation of these gestures.
