Without specifying any particular item or range of items, the various commands behave differently:

        Browse, Scan, Search:   All items
        Read, Yank:             New items
        all others:             Current, or most recently used item

However, there are many additional ways provided in which to express your needs to the system.  To specify which items you wish (where # is an integer):

        #               any item number
        #-#             a RANGE of values
        ,               to separate multiple RANGES

Other range specifying keywords include:

        new             brandnew items and new responses
        brandnew        entirely new items only
        newresp         old items with new responses
        free            items marked as no-charge downloads
