  -- Variable: tool-bar-map
      By default, the global map binds `[tool-bar]' as follows:
           (global-set-key [tool-bar]
           		'(menu-item "tool bar" ignore
           			    :filter (lambda (ignore) tool-bar-map)))
      Thus the tool bar map is derived dynamically from the value of
      variable `tool-bar-map' and you should normally adjust the default
      (global) tool bar by changing that map.  Major modes may replace
      the global bar completely by making `tool-bar-map' buffer-local
      and set to a keymap containing only the desired items.  Info mode
      provides an example.
