 * Acrobat menu items
 * Upon opening the page, create a full list of all menu item names in Acrobat.
 * With the spelling retrieved, the Acrobat menu item name can be used in PDFlib
 * actions to execute Acrobat menu items.
 * 
 * One of the retrieved menu item names can be provided in the "menuname" option
 * of the create_action() function to create an action of type "Named" for 
 * executing Acrobat menu items.
 * Create an action of type "Named" to execute the special Acrobat menu command
 * for opening the JavaScript console.
 * Create a JavaScript action to show the names of all Acrobat menu items in the
 * JavaScript console.
 * For the page trigger "open", supply the two JavaScript actions defined above.
 *
 * Required software: PDFlib/PDFlib+PDI/PPS 7
 * Required data: none
