Part and Chapter Names

I’m sure I’m missing something obvious, but I need to be able to name parts and chapters. I thought just by naming the folder that contained the documents that made up the parts and chapters it would name them appropriately on compile.

How does one edit or create such names. For example instead of:

Part Six

I want it to read:

Part Six
True Dark

Thank you for your time on this matter.

Best,
Micah

Read the friendly manual! That’s how you figure it out. I swear that wasn’t there before, but now I feel blind. Please have a good laugh at my expense.

I’m all set now.
