# Undo part of a change (/how-to/undo-part-of-a-change) Rewind takes the files back to how they were before a message you sent. You choose whether the conversation goes back too. See [Rewind to an earlier message](/conversations/rewind) for every option. ## 1. Find the turn that went wrong [#1-find-the-turn-that-went-wrong] Type `/diff` and use `left` and `right` to go through the turns, newest first. Each turn shows only the files that message changed. Note which message it was. ## 2. Open rewind [#2-open-rewind] Press `esc` twice with the prompt empty, or type `/rewind`. Move to the message that caused the change. Under it, Jinion shows what going back would change, such as `2 files change +29 -1`. Going back to a message takes back every file change made since then, in that turn and the ones after it. ## 3. Pick what to take back [#3-pick-what-to-take-back] Press `enter`, then: * **Restore code** to undo the files and keep talking. The conversation goes on as it is, so you can tell the agent what to do instead: ```text I took back your last change to the rate limiter. Keep the limit per IP, but read it from the config ``` * **Restore code and conversation** to start that message over. The files and the conversation go back, and your message returns to the prompt to edit and send again. Jinion confirms, such as `The files went back to how they were before “add a test for the window reset”; the conversation goes on.` ## Undo a single file [#undo-a-single-file] Rewind works per message. To undo one file only, ask the agent: ```text undo your changes to src/server.ts, keep the rest ``` Rewind only takes back changes made through the agent's file tools. A file changed by a command, such as a code generator or `git checkout`, stays as it is.
