Toggle between applications via four finger gesture?

Solution 1:

The best way to do this is with one of the more obscure settings in BetterTouchTool It works like this: A three fingered right swipe brings up the application switcher. Lift one finger to covert it into a two finger swipe and slide to whichever application you want.

It becomes an incredible natural and fluid gesture The beauty of the gesture is that it works anywhere on the screen and you don't have to position the mouse over the icons.

1. In BTT assign the three finger swipe right to the application switcher.
2. In BTT Action Settings -> Stuff(App Switcher) -> Use special application switcher

This answers the problem that bisko and senseful had above and avoids the last click or the necessity to be over the icon.

Single best gesture in my 'gesture vocabulary' and I have gestures for everything!

Solution 2:

Have you looked into BetterTouchTool? It lets you customize every touchpad input under the sun. You could for example remap the four-finger horizontal swipe to Cmd+Tab.

Solution 3:

On Mac OS 10.6:

1. Swipe with four fingers
2. Swipe or scroll with two fingers to select the application
3. Four fingers tap (no need to be over the app switcher) and it switches to the application you've selected.

Solution 4:

What about using the Command-tab keyboard shortcut for faster application switching than with the trackpad? Add the ability to quit or hide selected applications along the way by tapping Q or H. Or, use LiteSwitch X for more enhanced app switching.
