I'd like to move back and forward through the tab collection in Safari (or Chrome or FF) using trackpad gestures.
Does this gesture exist?
Using a 3 finger swipe (left and right) nicely moves you through the history of the current tab, however, I can't find a way to navigate through the entire tab collection with gestures alone.
You can use BetterTouchTool. It should be available for Lion in the next few days when the developer gets round to upgrading it. You can specify loads of custom gestures, almost everything you can find to do, can be mapped to a gesture or a keyboard shortcut.
Since Mac OS X version 10.5 ('Leopard'), you can use gestures to switch tabs in Firefox. Simply set browser.gesture.twist.left and browser.gesture.twist.right to Browser:PrevTab and Browser:NextTab in about:config.
The 'twist' gesture will now switch tabs in Firefox, assuming it isn't overridden by a global mapping in System Preferences > Trackpad.
For Safari
1 - Pinch In (As like you are zooming out)
2 - Use two finger to swipe left or right
Works for me on Safari 7.0.3
Move from left to right in open TABS:
⌘-⌥-→
From right to left:
⌘-⌥-←
Nope. You'd have to bind a gesture to the keyboard shortcuts. Something like Better Touch Tool (when it's Lion ready) can do that.
