Fork, reopen, close
Fork (⌘⇧F) starts a new session with the whole conversation so far, beside the original, which carries on untouched. It’s good for a side quest without losing your place.
- Where it opens: a perch terminal, unless Settings → Reopen sessions in names an editor (Cursor, VS Code…). Then a session running in an editor forks into a new terminal there.
- perch opens the fork as soon as it appears.
- Until you message it, a fresh fork shows the conversation it came from, titled “fork: …”.
Reopen after a restart
Section titled “Reopen after a restart”When your Mac restarts, perch offers to pick up the sessions you had open. Recently closed in the sidebar has the ones you closed in the last two weeks. Both open in a perch terminal, or in the editor picked in Settings → Reopen sessions in (only editors installed on your Mac are listed; they need the perch extension). It never opens the same conversation twice.
Close (⌘⇧W) stops a session after asking; Cancel is the default. The conversation is saved. ⌘⇧C copies the command to pick it up anywhere. Sessions in the Claude app close in the app.
