Use blank styles in Scrivener to mark text for revision without altering formatting. Blank styles serve as flags for sections you want to improve, such as dialogue, wording, or content repetition. Create them by selecting text without changing its format; apply and remove via the Style menu. You can search for text marked with these styles using the Find by Formatting feature.
