Which command does this run?  I can't reasonably input "^" from the
command prompt here.

Does it work if you set `resize-mini-windows' to nil?  If I do that
here, I can, for example, drag the divider between the emacs -Q main
window and the minibuffer window with the mouse.

The terminology "in the frame's other window" seems to indicate that
this was written in an earlier century.
