A Windows hook is fairly dark magic and essentially involves
adding a link into the chain of events whenever something
significant occurs within Windows -- mostly to do with the
Windows messages which are passed around between apps and
by the O/S. You really need to be sure you know what you're
doing before you launch out.

There's a useful-looking post here explaining how to
determine whether the Caps Lock is on or off:

but, frankly, except as a learning exercise, I think you're
trying to do something which is messy in the extreme and
far more fiddly than perhaps it appears from the human
perspective.

I fully expect you now to go ahead, do it easily and prove
me wrong! (In which case, we want a good write-up).
