FWIW, Icicles uses `C-insert' to switch back and forth between *Completions* and
the minibuffer. (Yes, that key sequence is not necessarily available on a
console.) "Insert" is relevant here (Icicles) because moving to the minibuffer
inserts the completion at point from *Completions*.

One possibility might be to make `C-x o' move to *Completions*. It currently
does not do that directly, but you can usually get to *Completions* by repeating
`C-x o'.

In general, it makes sense to use a key for this that is typically associated
with switching windows or buffers (e.g. `C-x o'), not a key that is typically
associated with scrolling (e.g. `M-v' or `prior' aka `PgUp').

And it makes sense to use normal scrolling keys (`C-v', `M-v') to scroll
*Completions*.
