AREASORT <sortspec>
        <sortspec> =
            A(ka)         : Sort by area aka.
            D(escription) : Sort by area description.
            E(choid)      : Sort by area echoid.
            G(roup)       : Sort by area group (if any).
            T(ype)        : Sort by area type (net/echo/local).
            U(nread)      : Sort by unread messages (try it!).

        This keyword defines how the area list is sorted upon
        initialization and when you change areas. If U(nread) is
        defined, the list will be sorted ascending by the number of
        messages left in the list. You can override the default
        setting from the command line with the -S<sortspec> option.

            Example: AREASORT TUE

        This sorts by Type, Unread and Echoid.
