[Key] ItemsList [Description] The ordered list of the subitems (actions or menus) attached to this menu. Each element of this strings list may be: the id of an action or a menu, a command to be executed, if the string is enclosed between square brackets ('['...']'). So, "ItemsList" key has a dynamic value: if an element of the string list is enclosed between square brackets ('['...']'), it is considered as a command, optionally with parameters and arguments, and so will be subject to an evaluation at runtime. If the standard output of the command is a valid strings list, then it is substituted to the bracketed element. It the command doesn't exist or cannot be executed, the bracketed element is just ignored. The keyword SEPARATOR is a special case of desktop_file_id. It may be used to define a separator in the menu. Actions or menus identified here as a subitem of a menu should not be redisplayed elsewhere. Actions or menus not identified here, or not identified as subitems of a menu or of a submenu, should not be ignored by the implementation; instead of that, the implementation should display these « orphan » items, most probably at the level zero of the hierarchy (though in a unspecified order).
