In Perl, one refers to the result of a match with $1, $2 and so on,
inside and outside the match.
There's one exception, when you want to use it in the match itself:
/(foo|bar)\1/
will match foofoo and barbar.

Well, in this case it doesn't matter much, since it's not Perl but
PCRE we're dealing with... OTOH, why not embed Perl in ctwm and use
real Perl to drive the configuration[1].

dynamic configuration depending on screen size, system type, what
windows are mapped, and so on.
