File - Up

          Up -- The File menu Up option changes the current
          directory to the next directory above the  current
          directory in the directory hierarchy.  It is
          equivalent to double clicking on the directory
          icon with the double dot (..) - the parent
          directory.  Alt+Shift+(u) or Meta+(f), (u) will
          change the current directory to the next higher
          (parent directory) in the directory hierarchy.
