How to create a single input field that copies itself into specif.

[KenE]

Want to reduce typing by allowing, say, a formal document identifier to be
typed onto the front page of a document and this field updates all instances
of that field in that document. In a multi-section document template, for
instance, the document identifier would be in all versions of headers and
footers but would need to be typed into each section separately - much faster
and efficient if this can be done using fields of some type.

Greg's article will suggest several ways to do this, but for your purposes I
think a StyleRef field would be the easiest, with a document property coming
a close second.
