Ordinal chapter numbering

Which placeholder tag must I use to have chapters numbered “First Chapter”, “Second Chapter”, and so on?

There’s a list of all the placeholders on the Help menu.

As far as I can tell, there is no placeholder for ordinal numbers, but you can have cardinal numbers using <$w> (or <$W> for all capitals).

E.g. Chapter <$w> gives you Chapter One, Chapter Two etc.
