Now *that's* a nice idea!

Agree.

To summarize my state of information: I think that the "ModX"
modifiers are just stand-ins in X11, in case a keyboard has a modifier
that is not in the regular list of "Shift", (Num)"Lock" and "Control".
So the "ModX" keys are generic to cover "Alt", "Meta", "Hyper",
"Windows", "Option", "Command", "AltGr", just to mention the ones of
which I have heard.

There seems to be a (probably later) interface to map these in X11,
and that interface is used in Tk/X11 and emulated in Tk for other
platforms.  So on Windows/Mac, as long as a "ModX" isn't already
taken, we can just use it, and "Mod4" just happens to be free on
Windows/Mac, I think.  It may not be free on all X11 implementations,
though.
