This would mean that sometimes the shell and sometimes the activity  
would have to handle that key, which is fragile. I'd opt for the shell  
always handling the key, then trying to invoke the activity's view  
source function, and if that fails, handle it itself.

That "not handled by activity" case could of course be customized by  
entries in activity.info.
