Rewind and branch

You can go back to an earlier message: change it and send it again, start a new tab from just before it, or put the files Claude changed since back as they were. Claude Code does the work (its checkpointing documentation describes it), and Claudette gives you the menu.

Your messages have a ⋯ button on their card header, shown while you point at the card or it has the keyboard focus. Its menu has Edit and resend…, Branch from here and Restore files to before this….

Edit and resend…

The conversation goes back to just before the message, and the message, with its images, goes into the composer for you to change and send.

Choose Edit and resend… on the message.
Read the confirmation. It says how many later messages are left out. If Claude Code kept copies of files from before the message, and some changed since, it also lists them and offers Go back and restore files or Go back, keep files. Otherwise there is just Go back.
Change the message and send it.

The tab carries on as a copy of the session, so the session as it was stays in History. It works only while Claude isn’t working, because going back in the middle of a turn would cut it in half. The menu says so in a note instead.

The first message of a conversation, and the first after /clear, has nothing before it, so going back to it starts a new session.

Branch from here

A new tab in the same folder carries the conversation on from just before the message, with the message in its composer. The tab you branched from is left as it is, and it works while that tab is busy. Branching from the first message opens a new session.

Restore files to before this…

Claude Code puts the files Claude changed since the message back as they were, and the conversation stays as it is.

Choose Restore files to before this… on the message.
Read the confirmation, which lists the files with their line counts. Later changes to them, Claude’s or yours, are lost.
Choose Restore files.

The tab’s claude has to be running, and Claude Code has to have kept copies. Without a copy, a note says why. If no files changed since the message, a note says that.

Duplicate tab

Duplicate tab, in the tab’s menu (The tab’s menu), opens a copy of the whole session in a new tab, or a new session in the same folder for a tab that hasn’t had a turn yet. Any copy keeps the tab’s settings, its kept quick suffixes, whether it syncs, and which files you marked reviewed.

It applies to tabs started after you change it.
