As new styles are added to the template, here's the place to find out what they do.

Body type: Drop Cap Rag Right Q
If you use a Q (such as for a Q&A) in the regular Drop Cap style the descender of the Q touches the top of the type below it. Using this style will call in a smaller point size for the drop cap and shift the baseline up so that lines up properly with the top of the first line.

Body type: Breakout with bold leadin
This is a 'nested style' that starts each paragraph in Breakout Bold until it reaches a punctuation mark, such as a colon. This can be helpful if you are styling breakouts that always start with bold type because you don't have to use character styles to make them bold. It does mean that if you don't use some sort of punctuation, the style won't work correctly.
