You don't need to switch or use the mouse.  You can instead:

  . keep typing TAB to scroll through the full list of completion
    candidates (if the full list takes more than a single window to
    show), or
  . type more text in the minibuffer, then press TAB again, to narrow
    the list of candidates -- the next letter which will narrow the
    list is displayed in bold in the list of the candidates, or
  . in Emacs 29, you can type M-<UP> and M-<DOWN> arrow keys to select
    the candidates

In Emacs 29, there's a new variable 'completion-auto-select', which
does precisely that.
