jitouch

jitouch is a Mac application that extends the multi-touch gestures available on the MacBook trackpad, Magic Mouse, and Magic Trackpad. It is designed to let users perform common actions with one hand, covering tasks such as switching browser tabs, closing or minimizing windows, changing spaces, middle click, full-screen maximizing, arranging windows side by side, moving and resizing windows, and showing desktop or Exposé on the Magic Mouse.

Its Character Gestures feature lets users invoke commands by drawing an English letter or a simple direction such as up, right, or up-right, combining multi-touch input with character recognition so gestures can be drawn anywhere on the trackpad without a preliminary listening gesture or a second hand on modifier keys. The application also includes separate Trackpad gestures and Magic Mouse gestures, and its gesture design is intended not to interfere with built-in system gestures. The homepage links to a download and a support section, but does not state a free plan, trial, or edition structure.
