Flow headings
Flow headings allow you to show the titles of flows immediately above their first system automatically. They function like templates, in much the same way as master pages.
Flow headings exist as part of master page sets. By default, Dorico Pro provides one flow heading in each master page set, which contains tokens to display the flow number and flow title; in a new project, this appears as “1. Flow 1”. This is used automatically for all flow headings, but you can insert flow heading changes to individual pages and ranges of pages.
Flow headings are automatically inserted above the first system of the flow to which they apply, meaning they do not have a fixed vertical position on the page like other frames and follow the music if it moves. They also occupy vertical space within music frames. You can change the margins for the space above and below flow headings on a per-layout and on a per-page basis by inserting flow heading changes.
When Frames is selected in the Engrave toolbox, frames in flow headings appear with dashed lines instead of solid lines to help you identify them. You can move flow heading frames in the same ways as moving any other frames, but this creates a master page override, which is a type of page format change.
