The various osXxx values tell the parent menu (or the main loop)
what to do. osEnd, e.g., tells it to close the current menu, osUnknown
means that the current menu didn't know what to do with the key,
and osContinue just means "don't do anything special, just continue".

So osContinue is what a menu that doesn't want to be closed should
return instead of osUnknown.
