Mh, it would be great to emulate something like ALT+TAB on a Desktop PC with the camerakey on N900.

Could it be possible to include this function in camkeyd without loosing the main functionality?

When you press the camera button in a application the dashboard appears.
When you press the camera button in the dashboard you reach the application you have used before your last application.

It would be nice to switch between 2 application only by pressing the camkey twice.
