13. A computer-implemented method for navigating a set of recordings stored on a handheld storage and retrieval device on a display of the handheld storage and retrieval device, comprising: on the display of the handheld device, presenting an initial screen for displaying only a hierarchical menu comprising only two hierarchical levels of a plurality of hierarchical levels of the set of recordings, the initial screen having initial headers representing a first one of the plurality of hierarchical levels and oriented according to a first orientation, said initial headers providing top-level categories for filtering the set of recordings, wherein each of said initial headers includes an association with a child list, whereby said initial headers form a band of lists represented by the initial headers; navigating the initial headers according to the first orientation; presenting a list of elements representing a second one of the plurality of hierarchical levels oriented according to a second orientation different from the first orientation, the list of elements associated with a currently selected header of the initial headers as a child list for the currently selected header; navigating the list of elements according to the second orientation; selecting an element from the list of elements; in response to said selecting the element, presenting a new screen having the list of elements as element headers displayed according to the first orientation, the element headers including the selected element as a new currently selected header of the element headers and displayed in an order determined by the selecting; and presenting a second list of elements representing a third one of the plurality of hierarchical levels and associated with the new currently selected header of the element headers as a child list for the new currently selected header, the second list of elements displayed according to the second orientation, the new screen displaying only the element headers and the second list of elements; and repeating navigating and selecting until a particular hierarchical level comprising atomic elements is displayed in the second orientation, wherein upon selection of an atomic element of the atomic elements, the display screen displays only the particular hierarchical level in the first orientation with the selected atomic element as an active header and an information display box containing information about the selected atomic element.
