Don't know, but Debian Code Search turns up a definition for `new page', .NP, in http://sources.debian.net/src/9base/1:6-6/troff/tmac/tmac.s/#L925 which is -ms from Plan 9, in case that helps anyone else looking. > Also, if I put .NP in my document, it has no effect, and no > warnings/errors are given.

See https://www.gnu.org/software/groff/manual/html_node/Warnings.html#Warnings $ echo .unknown | groff >/dev/null $ echo .unknown | groff -wmac >/dev/null <standard input>:1: warning: macro `unknown' not defined $ echo $? 0 $ Cheers, Ralph.
