There are two groff man pages, one for the binary (which is in
section 1) and one for the language (in section 7). Try
man 7 groff
which gives
\Z’anything’
Print <anything> and then restore the horizontal and vertical
position; <anything> may not contain tabs or leaders.
`info groff' has the same text (in section `Page Motions') plus this
example:
The following is an example of a strike-through macro:
.de ST
.nr ww \w'\\$1'
\...@\v'-.25m'\l'\\n[ww]u'@\\$1
..
.
This is
.ST "a test"
