All menus were always bound to down-events
C-down-mouse-1, S-down-mouse-1, C-down-mouse-2, C-down-mouse-3:

  (global-set-key [C-down-mouse-1] 'mouse-buffer-menu)
  (if (not (eq system-type 'ms-dos))
      (global-set-key [S-down-mouse-1] 'mouse-appearance-menu))
  ;; C-down-mouse-2 is bound in facemenu.el.
  (global-set-key [C-down-mouse-3]
    `(menu-item ,(purecopy "Menu Bar") ignore
      :filter (lambda (_)
                (if (zerop (or (frame-parameter nil 'menu-bar-lines) 0))
                    (mouse-menu-bar-map)
                  (mouse-menu-major-mode-map)))))
