Doing a Forum search reveals nothing, as does a Help Center search. The link under "Community" alludes to a Chapter 7 for Dynamic Lighting but links instead to "3 Starter Macros". Searching the Blog only pulls up Chapters 3, 4, and 5 (Turn Tracker, Macros, and 5e Character Sheet). This suggests that it's scattered through there somewhere, but I'm not about to plow through scores of pages of Blog posts looking for them. Sounds like a job for The Librarian.
