Ah, ha! "items like "0:20", "0:30" are exactly what WERE brought up -- and I mistakenly thought they represented sound levels! I just don't yet know how to interpret (or make sense of) them as "seeking" devices? Just one more reason why I need to apply myself and try to ferret out and comprehend all the wonderful nuances of Kagu. I will understand if, with all else you're currently dealing with, you ignore such (innane) queries of mine for awhile.
