      Commands marked with * may be preceded by a number, _N.
      Notes in parentheses indicate the behavior if _N is given.
      A key preceded by a caret indicates the Ctrl key; thus ^K is ctrl-K.

        Each "find close bracket" command goes forward to the close bracket 
          matching the (_N-th) open bracket in the top line.
        Each "find open bracket" command goes backward to the open bracket 
          matching the (_N-th) close bracket in the bottom line.

  m_<_l_e_t_t_e_r_>            Mark the current top line with <letter>.

        A mark is any upper-case or lower-case letter.
        Certain marks are predefined:
             ^  means  beginning of the file
             $  means  end of the file
