I was looking at http://www.apple.com/macosx/whats-new/gestures.html and I notices these changes: The right one: Switch between full-screen apps Click the top-right corner of a window to make an app full screen. Then swipe three fingers to see another full-screen app. Q: How does this work in full screen Safari, since it uses three-finger-swipe left/right to show the previous and next page? And does it still work as navigation when you're not in full screen? The right one: Tap to zoom Want to get a closer look at a website? Just double-tap the trackpad with two fingers to quickly magnify the page. Q: When you have "Tap to Click" setup for the trackpad, how does this work? Currently you can double tap (and thus click) to select text or whatever. Does this still work somehow, or do you need to physically double click to select something?
