Undo and Redo

Made a change you didn't mean to? No problem. StarZero Agents keeps a history of your recent edits so you can step backward and forward through your changes at any time.

How to Undo

You have three options:

• By conversation: Just say "undo that" or "undo the last change"
• In the visual editor: Click the undo button in the editor toolbar
• Keyboard shortcut: Press Ctrl+Z (or Cmd+Z on Mac) while the editor is open

Each undo steps back one change, restoring your project to how it looked before that edit was made.

How to Redo

If you undo something and then change your mind, redo brings it back:

• By conversation: Say "redo" or "redo that"
• In the visual editor: Click the redo button in the editor toolbar
• Keyboard shortcut: Press Ctrl+Shift+Z or Ctrl+Y (or Cmd+Shift+Z / Cmd+Y on Mac) while the editor is open

What Gets Tracked

Both conversation-based changes and visual editor changes are part of the same history. Whether you trimmed a clip by typing a request or by dragging a handle, it's all in the undo history. Each step is tracked with a description of what was changed and when, so you can always see what you're undoing.

Per-Project History

If you have multiple projects in a chat and switch between them, each project keeps its own undo/redo history. Swapping to an older project and coming back won't wipe the edits you made earlier -- your history is right where you left it for each project.

History Limit

StarZero Agents keeps up to 50 steps of edit history. That's usually more than enough for a working session. Once you go beyond 50 changes, the oldest steps are dropped to make room.

What if you need to go further back?

If you've run out of undo steps and need to get back to an earlier state, you have a couple of options:

• Ask StarZero Agents to recreate your project from a description or from an earlier version you saved
• Switch to a saved project file if you saved a version earlier in the session (using the project selector in the timeline editor)

This is why it's a good idea to save a version of your project before making major changes -- it gives you a safe point to return to.

Tips

• Undo early, undo often. If something doesn't look right, undo it immediately rather than trying to manually reverse the change.
• Save versions before big changes. If you're about to rearrange your entire project or make a lot of edits, save the current version first so you have a fallback beyond the 50-step limit.
• Undo works across both editing modes. It doesn't matter whether you made the change through conversation or the visual editor -- undo covers everything.
