Keyboard Shortcuts
Press F1 in Lacuna to open the Keyboard Shortcuts editor, found on the Hotkeys tab of Lacuna Settings. Every shortcut on this page is fully customizable, so you can rebind any of them to the keys that match your muscle memory, and Restore defaults brings them all back if you change your mind.
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?
Section actions (like Ctrl+Z for undo) only affect the section you’re currently editing.
Project-wide actions (like Ctrl+Shift+Z for project-wide undo) affect changes across your entire book, including section reordering, deletions, and metadata changes.
