I think the document referred to is Troff User's Manual Joseph F. Ossanna and Brian W. Kernighan CSTR No 54 (AT&T Bell Labs) Revised November 1992 (the reference for my copy) where on page 7 is a table of Escape Sequences for Characters, Indicators and Functions the last of which is - \Z Z, any character not listed above Thus "Z" in "\Z" is a dummy and does not stand for itself. (Of course, in that context it sould also stand for itself, since \Z [literally] was not an escape sequence in AT&T troff).
