Exit line edit-point mode before using the level-history shortcut.
Editor workflows
Undo, Redo & Editor History
Review recorded edits, undo a change or jump to an earlier state. Level edits, line-point edits and drawing edits have their own histories.
Creator guide
What you can build
Review recorded edits, undo a change or jump to an earlier state. Level edits, line-point edits and drawing edits have their own histories.
The options below are grouped by the way you use them. Available controls depend on the selected object, editor mode and enabled features.

Options and behavior
Find the control you need, then follow the setup steps to test it in a level.
History controls
| Option | What it does |
|---|---|
| History: right-side menu | Open the compact level-history panel from the right-side Level Settings menu. |
| History: line edit menu | Open the line-history panel from the end of LineEditPointControlsMenu while editing a physics line. |
| Ctrl+Z / Ctrl+Y | Undo or redo. In line edit-point mode these shortcuts act on the line history; otherwise they act on the level history. |
| Start row | Return to the state before the first recorded edit in the current history. |
| Select a history row | Jump to the state immediately after that step. Later undone steps appear greyed out. |
| Close history panel | Close the history list and reopen the menu it belongs to. |
| Level changes | Recorded actions include object moves, rotations, scales and settings, joint settings and supported level-setting changes. |
| Edit Group changes | Group history preserves the children, their offsets, transforms and order for recorded child edits. |
| Physics line changes | Record point and Bezier-handle movement, segment transforms, adding or deleting points, Bezier settings and segment changes. |
| Line-history lifetime | Line history is cleared when line editing opens and when it closes. It applies to the line currently being edited. |
| Draw Image history | Drawing changes use the image editor's own history. Open that editor's History control to review them. |
Creator guide
Try it in a level
Start with a small scene so each setting has a visible result.
- Make a small recorded edit, then open History in the relevant editor.
- Click the preceding row or use Ctrl+Z to restore the previous state.
- Use Ctrl+Y or a later row to restore the edit.
- Save the level or drawing when you want to keep the result; history is a way to navigate edits, not a saved-level backup.

If the result looks wrong
Use the symptom to find the next setting to check.
An old line edit is absent
