 exit fullscreen mode; 2) if in fullscreen mode and a page is loading, stop
 loading -- this is how Safari handles the esc case.

 the Activity class to handle this situation. In fact, I think it's not a
 good idea to modify the Activity class just for this special situation.
 Maybe we can think in something more general like defining a "state"
 (boolean) variable to add in the if clause.

 Remember classes and inheritance? :P You can redefine the callback (as we
 did in Terminal some months ago #440) Just remember to call the parent's
 callback.  Is a bit hackish because is a private method and have the name
 mangling with the two underscores, but I think doable.
