    '>>' like this, you can make more than one selection, concatenated
    with whitespace or comma.  Also you can say ranges.  E.g. "2-5 7,9"
    to choose 2,3,4,5,7,9 from the list.  If the second number in a

    Also when you are satisfied with the filtered result, press ENTER
    (empty) back to the main menu.
