 * 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 9

 * Required data: none
