Are you really meaning shift when saying S- (or maybe super? which is
usually not accessible to emacs unless you use it as a window manager
through exwm)? Then what is your keyboard layout?
In qwerty and dvorak: S-/ is ?, so C-S-/ is C-?, which is impossible to
type (it gives ? usually), while corresponding to DEL under a terminal.
In azerty: / is already accessed with shift.
In bépo: S-/ is 9, so C-S-/ is C-9 and is already bound to
`digit-argument'
