FWIW -

It can be typed on a tty, as `ESC-C-~'.  Admittedly, not as handy
as `C-M-~'.  But no worse than `M-s f ~' etc.

`~' is mnemonic for complementing/negation in some logic notations.

I use `C-M-~' because that is also the key I use for this in
Icicles search (from which this property-searching was taken).

In Icicles, `C-~' is used to complement the current set of
completion candidates, and `M-~' is used to toggle whether to
abbreviate your home directory using `~'.  And of course `~'
self-inserts.

> There is a special sub-map for filter commands on `M-s f'.

I have no objection, if you would like to put this on `M-s f ~',
for example.
