Opens the room-location list: replaces the menu strip with a pageable list of room names. Page 1 (room mode 2, entered here) lists rooms 0-16; page 2 (room mode 3, entered at 35228) lists rooms 17-33 — the Narcissus (34) is never listed. The 19 CorridorPosTable cells become: cell 0 = 62 "Other List" (switches to the other page), cells 1-17 = the seventeen room ids, cell 18 = 61 " QUIT " (returns to the orders screen). The cursor starts on QUIT. While the list is up, the action key dispatches straight to LocationListAction (35338) via RoomDispatchTable entries 2/3: picking a room draws its deck map in the map pane with the room's indicator box blinking on it (marker channel B).
