 Replying to [comment:1 scribu]:

 automatically from $page_title.

 No, I'm not referring to the `$menu_slug` parameter, but the id of the
 sublevel page. This id seems to be generated from the top level menu title
 and thus will it change when you translate that.  Example:

 {{{
 add_action( 'admin_menu', 'example_menu' );

 function example_menu() {
         add_menu_page( 'Toplevel title', 'Toplevel nav', 'manage_options',
 'toplevel_slug', 'example_toplevel_page' );
         add_submenu_page( 'toplevel_slug', 'Sublevel title', 'Sublevel
 nav', 'manage_options', 'sublevel_slug', 'example_sublevel_page' );
 }

 function example_toplevel_page() {
         $screen = get_current_screen();
         echo $screen->id; // toplevel_page_toplevel_slug
 }

 function example_sublevel_page() {
         $screen = get_current_screen();
         echo $screen->id; // toplevel-nav_page_sublevel_slug
 }
 }}}

 When make the menu_title argument in the add_menu_page function call
 translatable, I enable the translator to change the `$screen->id` variable
 on all submenu pages, as the `$menu title` argument of the toplevel menu
 item gets prefixed to that id.
