Keyboard Shortcuts
Press F1 in Lacuna to open the shortcut viewer. Every shortcut on this page is fully customizable, so you can rebind any of them to the keys that match your muscle memory.
Every shortcut also maps to a button in the editor toolbar, so you can pair both for the fastest workflow. Use find and replace text in your book when project-wide changes are easier than per-section edits.

What’s the difference between section and project-wide actions?
