How do you create a Font menu?

Simply create a new menu and name it "Font". That's it. Whenever this is inserted into the menu bar (or into a menu item as a submenu), SuperCard will automatically generate a list of currently installed fonts and attach them to the menu, generating an itemSelect message which it sends to the menu. To find out which font the user selected from the menu, query the textFont property - SuperCard updates this property for you when an item is selected from a Font menu.
