I'm hacking troff code, and I come across a number of constructions
that use <Ctrl-G> characters, such as the examples below:

	.if\w^G\\n(}Z^G .nr A 3 '
and

	.if^G\*(]S^G^G .ds ]S \s14\f3\*(}Z\fP\s0

and

	.if^G\\$1^G2^G .if !^G\\$5^G^G .ds }i\^

I suppose I'm missing something fundamental here, and I can't find any
help from the manuals (hah!).

Please enlighten me, or tell me from what source I might find
enlightenment.
