Click or pinch to see your tabbed web pages

The latest version of Apple’s Safari web browser offers a new, eye-popping way to view your open browser tabs—provided you’ve updated your Mac to “Mountain Lion,” that is.
Just click the new “show all tabs” button in the top-right corner of the Safari 6.0 interface, and presto: your tabs will simultaneously shrink and spread into a row, giving you a bird’s-eye view of all your tabbed web pages.

Just click the “Show all tabs” button for a bird’s-eye view of your tabbed web pages.

Got a MacBook? If so, there’s another way to activate the new “Tab View” mode: by “pinching” your trackpad while the Safari window is active.
Next, try tapping the arrow keys on your Mac’s keyboard or swiping left or right on your trackpad to cycle through your various tabs.
Find a tab you want to view? Just click it, and it’ll expand to fill the Safari window.
Can’t find the “Show all tabs” button on your version of Safari? That’s probably because you haven’t installed Apple’s “Mountain Lion” system update on your Mac yet.
While you can install Safari 6.0 on a Mac with the older “Lion” system software (just click the Apple menu in the top-left corner of the screen and select “Check for updates”), you won’t be able to turn on “Tab View” until you make the leap to “Mountain Lion.”
