Agreed, though there is one thing in there that would be very helpful  
to me if it worked, and that is an example of how to intercept events  
(I'm interested in keyboard events in particular but I'm pretty sure I  
could extrapolate from mouse events).  I'm sure I can figure it out on  
my own but a working example would save me a lot of slogging.
