Use Gestures To Go Back & Forward in Many Mac OS X Apps
Mac OS X has a myriad of multi-touch gestures that have been expanded upon in modern versions of Mac OS X, and one of the better gestures is the two-fingered swipe left or right to go either back or forward in a wide variety of apps.
This gesture is borrowed from the iOS world and it’s quite useful as a back / forward quick action.
You’ll obviously need a trackpad or Magic Mouse to be able to use these, and they’re supported in a fair amount of Apple apps like Safari, Dictionary, iTunes, App Store, Launchpad, and just about any other app where there’s a forward or back button.
Place Two Fingers on the Trackpad and Swipe Left to Go Back
This gesture can replace the back button basically.
Place Two Fingers on the Trackpad and Swipe Right to Go Forward
This gesture offers an alternative to the forward button.
For browsing, the gesture can be much faster than navigating to a back or forward button since all it takes is a quick flick to activate.
Unfortunately not all apps support the back/forward gesture yet, but with heavy iOS influences coming to the Mac you can bet more and more apps will support this and others soon. Many iOS apps support the same ability.
On a side note, if you’re used to hitting the Delete key to go back a page in Safari and don’t want to use a gesture, that behavior can be restored to the Delete key with a defaults command.
This works in Mac OS and Mac OS X beyond versions 10.8, anything modern will have this ability.
