also keeps the notion of an activeScript. All object events are
passed to the associated script for that application, regardless if
the application has keyboard focus or not. All keyboard events are
passed to the active script only if it has indicated interest in the
event.c C s t i i | t i | _ h | _ h | _ d | _ t

caret moved, etc.
