How do I undo the last operation in jj?▼

Undo the most recent operation in jj by running `jj undo`. This reverts your repository to the state before that operation, whether it was a describe, squash, split, or commit, while preserving your working copy.

Can I undo multiple operations at once in jj?▼

Yes, undo multiple operations by running `jj undo` repeatedly to step back through your operation history. Each command reverts one operation, letting you walk back safely through a chain of changes.

How do I redo an operation after undoing it in jj?▼

Redo undone operations by checking `jj op log` to view your operation history, then use `jj op restore` with the operation ID to restore to a specific point in time and reapply previously undone changes.

What happens to my working copy when I undo in jj?▼

When you undo an operation in jj, the repository state reverts while your working copy remains consistent. Auto-snapshots before each operation ensure you can safely step back without losing uncommitted work.

What's the difference between `jj undo` and `jj op restore` in jj?▼

`jj undo` reverts a single recent operation quickly. `jj op restore` restores your repository to any specific point in the operation log using its ID, giving you more precise control over which past state to return to.
