Capturing any Key Event on Your Phone
The keycapture module offers an API for global capturing of key events. With this module, you can react to key events even if some other S60 application is active and your PyS60 program is running only in the background. For instance, you could have a key combination that triggers an action regardless of the application that you are using on the phone.
The keycapture module provides a KeyCapturer object that is used for listening to the events by way of a callback function. The callback is called each time any of the specified keys is pressed.
Since capturing all key presses on your phone has security and privacy implications, 3rd Edition phones require a special capability (SwEvent)to use this module. See Appendix A for more information about capabilities.
