What’s Covered in This Codex Cheat Sheet (August 2026)
Codex is OpenAI’s coding agent: a Rust CLI with a full TUI, plus a Codex workspace inside the ChatGPT desktop app. Bindings below are checked against OpenAI’s slash command docs and the desktop Commands reference. ChatGPT-only keys (temporary chat, Quick Chat) stay on the ChatGPT page so this URL targets Codex search intent. Use Ghostty or Warp if Shift+Enter newlines misbehave in your terminal.
