Opening an app from another app

I’m programming applications for a D70 using the API and I need to know: is it possible for one app to open up another app? For example, could I set one of the softkeys within the demo Caller ID app to, when pressed, open a different application?
Thank you in advance.


You’d probably need to fire an event, background your current app and then, assuming your other app has been started, observe the event and the foreground itself.
