Docs / Editor Basics
Undo, redo & revision history
Two safety nets: in-session undo, and saved version history.
Ctrl+Z / Ctrl+Y (or the buttons in the top bar) undo and redo changes within your current editing session, exactly like most editors.
Separately, the History panel (top bar) keeps a real saved history: every time you save, Craftor snapshots the version that's about to be replaced. If you close the tab, come back a week later, and want to roll back, open History and restore any past version — restoring itself creates a new snapshot first, so restoring is never a one-way trip.
