What's in this Muse Code cheat sheet
Muse Code is Meta's terminal coding agent (muse CLI), built on Muse Spark. It is not the consumer Muse app that launched on iPhone and Mac in September 2026. This page lists the keys and slash commands from Meta's working with the agent, rewind, and workflows docs. Run /keymap in your session if a newer build added bindings.
Last verified 19 September 2026. Windows and Linux share Alt chords. On macOS, Alt becomes Option. Voice input is Mac-first. Workflows depend on the build — Meta notes the public Apple silicon package may omit the workflow engine, so /workflows can be missing there.
The one thing to know first
Four keys get mixed up in every new Muse Code session. Enter steers the current turn. Alt+Enter queues for the next turn. Esc stops only the turn — not background work. /stop stops background terminals. Official docs bury those in a long essay; the tables below put them first.
