I think I'm getting confused here:
I created the New style but there is no way to apply both a bold font and an unbold font to a caption without manually going through and highlighting either the bold or unbold font.

You said earlier that the style set will not unbold a font so that is why the caption style was modified to produce unbolded font.

Here is where I interpret the new style 'CaptionLabel' incorrectly:
It sounds as if it will be used to bold only the label part of the caption and leave the body alone. But creating a new style using character type and clicking the bold button produces the entire caption in a bold font.

To clarify the inference here:
The TC posted an attachment with the caption having a bold label and a normal font.

This looks much better than the entire thing bolded and is the formatting required for this class.

To clarify my original understanding of the TC problem:
Is it possible to create a caption similar to the example just given.
When I say is it possible, I mean is it possible without manually changing each occurance.
I think the last statement will clear up any misinterpretation between myself and the operation you described earlier. Thanks!
