In plain terms: a scene break is a small marker within a chapter that tells the reader "time or place is jumping here" — without starting a whole new chapter.

You've seen them in novels: a little gap, three asterisks * * *, or a small decorative symbol centered on its own line.
The common styles
- Blank space — a simple gap.
- Asterisks or a typographic symbol —
* * *, a dash, or a dot leader. - An ornament — a decorative flourish such as ❧ or ✦.
- Numbered — each scene headed by a roman numeral.
How Bookbndr finds them
In your manuscript a scene break is usually a line with just a few asterisks, or an empty paragraph used as a divider. Bookbndr detects these and replaces every one with the single style you choose — so they're perfectly consistent throughout the book.
