No, I did not as I have no idea when this started happening (it's a key
that I did not use for a long time).

I have, however, sort of figured out what is happening: the Windows key
acts as "super" in Emacs and it seems to do so no matter what I tell the
system via xmodmap.

So, if I type "C-h c WINDOWSKEY d", I do get "s-d undefined" so the key
is being interpreted, just not as what xev and other tools say it is
(i.e. as F20, as I defined it using xmodmap).

So, somehow, maybe, Emacs is interpreting the *keycode* instead of the
*keysym*?  Maybe something in the X11 parts of the Emacs code.
Somewhere to look, in any case, so I'm still investigating.

I have no need for a "super" key as I try to avoid all forms of key
chording as much as I can due to RSI issues.

Thank you,
eric
