/**

 *            to this menu item. This will be used as the key in the

 *            the "New" item on the "File" menu would have a menuPath of
 *            File->New->Graph Editor. Delimeter is "->" (no quotes), and
 *            spaces are allowed within menu text strings, but not around
 *            the delimiters; i.e: New->Graph Editor is OK, but File ->New
 *            is not.
