Mac trackpad If you use the multi-desktop Spaces feature of Mission Control often, you�ll probably like a hidden gesture in Mac OS X Lion that lets you immediately jump back to the most recently used Space with just a four-fingered tap on the trackpad (or Magic Mouse). Here�s how to enable the gesture with a defaults write command.

Launch Terminal from /Applications/Utilities/ and enter the following command:

defaults write com.apple.dock double-tap-jump-back -bool TRUE;killall Dock

Go to a different desktop and perform a four-fingered tap to immediately switch back to the previously used Space. You�ll obviously need to have multiple Spaces open for this to work, and once you get used to it, it�s a very nice addition to the other Mac gestures.

Disabling the gesture can be done by entering the following defaults write command into the Terminal:
defaults delete com.apple.dock double-tap-jump-back;killall Dock

This is a tip found on CultofMac written by Keir Thomas, who recently wrote some cool posts for us and also authored the book Mac Kung Fu.

Thanks for sending this in Torsten!
