line feed
     
         (LF, control-J, {ASCII} 10) The {ASCII} character
        meaning move the {cursor} down to the same column on the next
        line.  Originally this would have been done by "feeding" paper
        through the printer.
     
        {Unix} uses line feed as its text line terminator ({newline}
        character).
