Navigate & Flip Through Open Browser Tabs with Gestures in Safari 6
Safari 6 has a great new way to quickly navigate through open browser tabs using gestures. To access the new tab preview screen, either use a two-fingered pinch inwards, or click the little box on the far right of the tabs:
Once in tab previews, use a two-finger gesture left or right to flip between open tabs. Click on any preview to immediately open that tab.
You can also hit Command+Shift+\ to get to the same tab view, and then use the keyboard arrow keys to navigate between the tabs.
This feature is new to Mac OS X but it’s fairly similar to how Safari on iPhone behaves when you’re switching between tabs and should be familiar to anyone who comes from an iPhone background.
Safari 6 comes with OS X Mountain Lion and is available for Lion users as well.
