Dag-Erling, good day. Speaking for the system's nvi (not the ports one -- not using it).

But ':%s...' is shorter to type ;)) Moreover, "1," will select lines from the first one to the current one. And, for example, ",+3" will select four lines, counting from the current and going down; "-2," will select three lines, counting from the current and going up. > None of this is documented anywhere. $ zcat /usr/share/doc/usd/13.viref/paper.ascii.gz | less and search for the 'percent sign'. -- Eygene _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
