Spread Controls let you manage both pages of a spread with one set of controls.
Changing Individual Spread Controls: Use the Spread Controls toggle at the top of the assignments panel to turn spread controls on/off for individual spreads.
- This is equivalent to pressing Ctrl/Cmd and clicking the second page to select both pages at once.
- Toggle spread controls off to return to individual page control.
Changing Book-Wide Default: Advisers and editors can make Spread Controls the book-wide default under Settings > Preferences > Edit > Spread Controls in Book > Default to Spread Controls
