                                Line Numbers

        A  LINE  NUMBER  refers  to  a line in the edit buffer.  The
        lines are always numbered sequentially starting with  1.   A
        line  number can be expressed as an integer, as "."  meaning
        the CURRENT LINE, "^" or "-" meaning  the  line  before  the
        current  line,  "$"  meaning  the  last  line,  as a PATTERN
        enclosed in "/" slashes for a forward  scan,  as  a  pattern
        enclosed  in "\" back slashes for a backward scan, as a MARK
        NAME preceeded by "<" for a backward search or by ">" for  a
        forward  search, or as any additive combination of the above
        by joining them with operators "+", "-", or nothing (meaning
        "+").

        Type "hlist" for line number list syntax.
        For details on scans and searches, type "hscan".
