At the beginning of each chapter, the first paragraph is not indented (which is great). However, what if I want to add a line before that which too is not indented?
Something like…
Saturday, Dusk
Newport Beach
First para… (not indented)
Second para… (indented)
That can be done having the first part in a separate document and by using a different section type & section layout.
…Or by cleverly using line feeds instead of carriage returns, so that your first four lines (that’s including the empty one) are actually all part of that first paragraph. 
RTFM if necessary, only after watching all the Literature & Latte videos on the subject.
