I nevertheless checked it in to allow others basic navigation.  I'll
look into the minibuffer case later.

Certainly not (the function I use was too complex to post here): Try

(defun select-window-on-left ()
  "Select window on the left."
  (interactive)
  (let ((window (window-in-direction 'left)))
    (when window (select-window window))))
