Comment(by humitos):

 Replying to [comment:4 garycmartin]:
 > Something like 1) if in fullscreen mode and a page is not loading, exit
 fullscreen mode; 2) if in fullscreen mode and a page is loading, stop
 loading -- this is how Safari handles the esc case.

 Well, this is not so easy to do because in that case we have to modify 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.

 At the moment, Sugar's Activity class take priority over the "key-press"
 event (sugar3/graphics/window.py L250). So, if we are loading a web page
 in fullscreen and we press Esc, we will be "unfullscreen" and the web page
 will keep loading.
