OK, but I wouldn't want to contruct a completely new menu-item, I would 
just want to exchange the text. Now, when I do something like

(lookup-key global-map [menu-bar file open-file])

all I get is the pure command, 'find-file-existing, in this case - but 
not the arguments :enable and :help that were defined in menu-bar.el:

(define-key menu-bar-file-menu [open-file]
  '(menu-item "Open File..." find-file-existing
              :enable (not (window-minibuffer-p
                            (frame-selected-window menu-updating-frame)))
              :help "Read an existing file into an Emacs buffer"))

So in order to _change_ single elements of a menu-item, I need to read 
out everything that define-key was called with in menu-bar.el.

Of course, I could tinker with menu-bar.el directly or copy stuff out 
of it, but that would be no fun to keep up to date...

Thanks in advance
