I'd like to try to adapt this to my macro but I can not find the
definition of Z anywhere. Not in man groff, not in man grops. What
does it do?
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'
address@hidden'-.25m'\l'\\n[ww]u'@\\$1
..
.
This is
.ST "a test"
an actual emergency!
