Using a method similar to that used to activate regular submenus, you can activate or deactivate a pull-down or cursor submenu by using $Pn=xxx. Variations specific to POPn menu sections are explained here and use the following format.
$Pn.i=xxx
where
| $ | Loads a menu section |
| Pn | Specifies the Popn menu area |
| i | Specifies the menu item number |
| xxx | Specifies a string of grayed-out or marked characters |
