Somehow I expected that response from you. ;-)

The fact that "alt RET" works does not mean that an entry for the right alt key
would not _also_ be helpful.  E.g., "right alt key".

And as I suggested, entries for "ctrl" and "control" might also help here.

Think of Le's question as an index search: "Why doesn't left-control plus
right-alt work for `C-M-'?".

That's a reasonable question, especially given that using left keys for both
control and alt and using right keys for both of them work as expected - each
combination is interpreted as `C-M-'.  And just the right alt key alone also
works, as `M-'.  It is only the combination left control plus right alt that
Emacs treats by default as control + altgr.

(defcustom w32-recognize-altgr t
  "Non-nil means treat keys right-alt and left-ctrl used together as AltGr.
If nil, treat the combination the same as ctrl plus alt (typically
`C-M-')."
  :group 'keyboard :type 'boolean)

For any C code (the defvar is in `w32term.c'), someone else will need to
contribute.
