MARK

  Puts an invisible mark at the current position. Later, using GO TO, you
  can return to the marked location. This makes it easier to move through a
  large file or buffer or between buffers.

  Example:

     The following commands put an invisible mark at the current position,
     naming it CHAP ONE, and later return to that position:

        Command: MARK chap one
                   .
                   .
        Command: GO TO chap one

  Usage notes:

  o  Marker names can be one or more characters, including spaces and tabs.
     Also, the names are not case-sensitive (you can use uppercase,
     lowercase, or mixed case). Wildcard characters in marker names are
     treated as regular characters. For example, you can have a marker
     named *.

  o  To check names of markers in the buffer, use the SHOW command.

  o  Markers are NOT saved in the output file from session to session.
