menuconfig: Add jump keys to search results
makes it possible to jump directly to the menu for a configuration entry after having searched for it with '/'. If this menu is not currently accessible we jump to the nearest accessible parent instead. After exiting this menu, the user is returned to the search results where he may jump further in or elsewhere.
