In SnowLeopard: 2 finger LEFT/RIGHT = scrolling the page left and right (if there is a horizontal scroll bar) 3 finger LEFT/RIGHT = Page BACK/Page Forward (In any browser AND in Finder windows) In Lion: exact SAME THING. I had to go to System Preferences > Trackpad and change "Swipe between pages" from "2 fingers LEFT/RIGHT" to "3 finger LEFT/RIGHT". So it is now exactly the same as it was in SnowLeopard. Wasn't it advertised that you can go page back/forward with 2 fingers? Why doesn't 2 finger left/right work in Finder/ANY browser and only work in Safari with cool animations..... but when I change it to 3 finger left/right, it works universally??? Why wont the default setting of "2 finger swipe between pages" work in finder windows I dont get this..
