Making submenus is easy -- just create a SwitchMenu on a content screen/page of another!
You can even make sub-submenus, or sub-sub-submenus.
The SwitchMenus are not aware of each other--note how switching from page to page on the root menu does NOT reset any of the submenu pages.
ScreenSwitch tracks which screens are displayed each time you click a link.
Using the back button on your browser will bring up the last screen settings in place, regardless of how many menus you have nested.
Note that the default page settings were not recorded--there is a command that will fix that detailed in a later example.
