OS X Lion's new Multi-Touch gestures have switched things up more than any previous version of OS X, and they're brought a lot of confusion with them. While "natural" scrolling is the most obvious change and the one that takes the most getting used to (unless you disable it), other inconsistencies in the way Lion handles Multi-Touch gestures are both more subtle and potentially more baffling. The one that's been tripping me up even after almost two weeks of using Lion is the gestures for going forward and back in Safari and other applications.
