The %s state value is OS/wm dependent, so there is no standard
meaning to the bits.

Much more portable is to bind all of the modified events
(<Shift-1>, <Alt-1>, <Ctrl-1>, <Ctrl-Shift-1>, etc)

It would be a very useful enhancement if Tk gave a uniform
state string with events (most conveniently, in exactly the
format used to create bindings: "Ctrl-Shift-", or even combined
with the keysym "Ctrl-Alt-Return")
