yes, I think you can - I expect Gdk picks up this stuff and turns it
into GdkEvents all right. The stuff I'm intending to drop is setting the
pointer shape (what Gtk calls internally "the cursor", which is
confusing). So, for example, you used to be able to set a particular
pointer shape ("cursor") when dragging with the right-button with
CapsLock on. I'm pretty sure no-one has ever made practical use of it
though. 

I don't think there is a lot of scope for setting the mouse shortcuts
with so many of them being hardwired, but I'm not taking anything away
from that code. Again, I haven't heard of people actually doing this - I
think it is still the case that you can insert crescendi using
left-button-dragging and caps lock, but it doesn't seem to be useful in
practice.
