Hi Kirk,
It's in the IPTC stationery pad. In the caption box and others. When I'm setting up the stationery pad some words are used many times over and some need to be formatted as all caps, all lowercase, or first letter caps. So I either have to copy each version in Pasteboard (that's a great program BTW), or do it manually. It works in Lightroom and most other programs I work with.
