 | `stayInAutopilot` | Keep the CLI in autopilot mode after an autopilot task completes, instead of returning to interactive mode (v1.0.69+) |
 | `defaultMode` | Startup mode for new interactive sessions (e.g., `interactive`, `autopilot`, `plan`) (v1.0.81+) |
 | `defaultPermissionMode` | Default approval behaviour for new interactive sessions, independent from `defaultMode` (v1.0.81+) |
+| `editorMode` | Set to `vim` for modal editing (normal/insert modes) in the composer (v1.0.84+) |
 
 > **Note**: Older snake_case names (e.g., `include_gitignored`, `auto_updates_channel`) are still accepted for backward compatibility, but camelCase is now the preferred format.
 
+> **Vim mode (v1.0.84+)**: Toggle modal editing in the prompt composer with `/vim`, or set `editorMode` to `vim` in your configuration to enable it by default. The current mode (normal or insert) is shown while you type.
+
 > **Session restore after a crash (v1.0.81+)**: If the CLI is interrupted unexpectedly — a crash or a machine restart — startup now offers to restore any sessions that were still open, so you don't have to reopen each terminal by hand.
 
 > **Piping an auth token (v1.0.81+)**: Use `copilot login --with-token` to read an authentication token from stdin instead of going through the interactive browser or device-code flow — useful for scripted or containerized setups where a token is already available in the environment.

 From the app, you can request a Copilot code review on a pull request—and re-request a review even from reviewers who already responded—without leaving the session. This keeps the review loop inside the same workspace where the change was made.

 ### Launching Sessions from the Terminal with Deep Links
 
 > **New (v1.0.81+)**: Run `copilot app` from GitHub Copilot CLI to open the GitHub Copilot app directly in the current directory — a quicker alternative to constructing a deep link by hand when you just want to hand off your current working directory to the desktop app.
