25 ;; Avishai Yacobi suggested some menu rearrangements.
27 ;;; Commentary:
29 ;;; Code:
31 ;; Don't clobber an existing menu-bar keymap, to preserve any menu-bar key
32 ;; definitions made in loaddefs.el.
37 ;; Force Help item to come last, after the major mode's own items.
38 ;; The symbol used to be called `help', but that gets confused with the
39 ;; help key.
45 ;; This definition is just to show what this looks like.
46 ;; It gets modified in place when menu-bar-update-buffers is called.
58 ;; Only declared obsolete (and only made a proper alias) in 23.3.
61 ;; This is referenced by some code below; it is defined in uniquify.el
64 ;; From emulation/cua-base.el; used below
