    What still bothers me in `Query Replace' is that `C-M-%' is not
    mentioned.  Lute added a comment saying that it can't be typed on
    consoles.  But is it a reason for majority of users (X, xterm,
    MSWindows, MacOS) to not know about `C-M-%'?  Users who can't type
    `C-M-%' on consoles, have other means (manuals, help facility) to find
    a replacement command.

I would not mind mentioning it, if there is room.
