First, open the Extension Manager (Tools Extensions), select the Mouse Gestures extension in the list, and click the Options button at the bottom to open the Mouse Gestures options window. In this window, click the Edit Mappings button at the bottom of the General tab to open the Edit Gesture Mappings window (where gestures are mapped to the Firefox commands they perform). Next, click the New button to open the New Gesture Mappings window. Now, to define your gesture, you need to specify two things: the gesture itself, and the Firefox command it performs (e.g. minimize window). The easiest way to specify the gesture is to click the Recognize button next to Gesture Code and perform the desired gesture (using the right mouse button, as with all gestures) in the white screen that appears. Then choose the Firefox command to perform from the Functions list at the bottom of the window. When finished, click OK, and then click OK again to close the Edit Gesture Mappings window and the original options window. Your new gesture is ready to go! Tip You can share your gesture with the world at the Gesture Exchange (http://optimoz.mozdev.org/gestures/redirect/gesture-exchange/). You can also see what your fellow gesturers have come up with - and even install their gestures! When you find an intriguing gesture, simply click the link to it, and then click OK when the Import Gesture Mapping window appears. You can start using the new gesture immediately; no restart is required. REMEMBER Release the right mouse button when you finish a gesture. If you continue to hold it, the gesture will be cancelled. How it works After installing the Mouse Gestures extension, you're ready to go. Navigate to a few Web sites so you have some browsing history and then try the Go Back gesture. A note appears in the Status Bar as soon as the gesture is recognized. You can configure mouse gestures from the extension's options window, which you access by selecting Mouse Gestures in the Extension Manager list (see Chapter 20) and clicking the Options button at the bottom. To create or change gestures, click the Edit Mappings button at the bottom of the options window, and note the key in the bottom left so you can follow the chart. You can also turn on a neat feature called mouse trails on the Visual Settings tab to have a line drawn on-screen each time you gesture. This feature is handy when you're getting acquainted with gestures because you can see exactly what the extension "sees" and discover how to perform the gestures it doesn't recognize more precisely. In Figure 22-3, I'm performing a Go Back gesture. (I didn't draw a very straight line, but the Mouse Gestures extension recognized it anyway.) Just be sure to read the note about this feature on the Visual Settings tab. Figure 22-3: Turn on mouse trails to see the gesture on-screen as you perform it.
