C-h map is quite full, and "C-h h" is already taken, so this proposal
is a no-go.

I suggested "C-x 4" because it is a prefix we use for many "do stuff
in other window" commands, and this is a logical extension of that
repertoire.  "C-x 4" is also convenient to type, and people who, like
me, are used to invoke many "other-window" commands will get used to
it instantly.  Most importantly, "C-x 4 h" is free for grabbing.
