Bug#395052: Please provide the GTK frontend with a better handler for BOOLEAN questions
One more thing: please evaluate if it's better having the active by
default radio button focused, so that the user has to move up/down with
the arrows and then press enter, or if it's better having the focus on
the inactive button.
I assigned focus to the inactive radio button, so that i can simply
press spacebar with the thumb and hit enter with the middle finger
without using the arrow keys, but i'm not sure this is not confusing.
