Multi-Touch gestures in any application

Apple's Multi-Touch technology from iPhone and iPod touch has trickled down into the MacBook Air and most recently into the MacBook Pro. The gesture-based trackpad technology allows you to pinch, swipe, or rotate to enlarge text, advance through photos, or adjust an image.

Ever wish that you could do even more than that though? Swipe to change tabs in Safari or iChat? Zoom-in to open email, zoom-out to close windows in every application or swipe down to bring up Quicksilver? Now you can.

Will Henderson's MultiClutch is free Preference Pane that allows you to assign custom keyboard shortcuts in a given app to a given gesture. MultiClutch installs an input manager that catches gesture events, looks to see what shortcut you’ve defined for it in the frontmost application and performs that shortcut.

You can define gestures for any Cocoa application (Carbon apps are not supported) or globally. In addition to the four swipe directions, zooming in and out and rotate in either direction, Henderson has been experimenting with combobination gestures like "Zoom in, Zoom out" (in one fluid motion) and visa-versa, with more perhaps to come.
