Thanks for putting your technique together in a nice format like this! Just so you know, I’ve moved this to the tips board, as it was in tech support.
By the way, if you want to write about Scrivener’s various placeholder tags, there is a way to “escape” these so you can print them as they should be typed in. Just insert a backslash before the opening ‘<’ symbol. For example, <$n:Chapter>. The backlash will be stripped out when you compile, leaving just the code as text for your readers.
Another feature you might appreciate is Replacements. I described a technique for building captions from a simplified code that you use while writing. We have a few examples of these in the Non-Fiction project template, for figure and table numbering. They are documented in the “about” file at the top of the binder.
The option is in the Transformations compile option pane, near the bottom: Remove text color.
