Jump to the Most Recently Used Desktop Space with a Hidden Gesture in OS X Lion
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
