C-p and C-n in the minibuffer should do what they
do normally.  The minibuffer is a text-editing
buffer, and it can have multiple lines of text.

(For minibuffer history we have M-p and M-n instead.)

FWIW, in Icicles the `up' and `down' arrows do cycle
among completion candidates.

And `C-up' and `C-down' cycle and act on each candidate,
in turn.  (You can apply the same command to multiple
candidates, in any order.  Cycling follows the current
sort order.)

And `C-M-up' and `C-M-down' show help on each candidate,
in turn.

And `C-wheel-up' and C-wheel-down', and same with `C-M-',
do the same kinds of cycling.

And `C-S-up' and `C-S-down' are like `C-up' and `C-down',
but they use an alternate action.  And likewise, with the
mouse wheel.
