Default keyboard shortcuts on Mac, Windows and Linux

The default recording hotkey is Option+Space on Mac and Ctrl+Space on Windows and Linux. Press it once to start dictating and again to stop.

Toggle and Hold share one hotkey. Switching to Hold to Record keeps your current hotkey. See Choose Toggle or Hold to record.
Context hotkeys only work for contexts you have turned on. Built-in contexts other than Default Transcription are off until you enable them. See Turn on built-in contexts like Email and Slack.
See your current shortcuts on the Dashboard, on each card in Contexts, or in Settings > General > Keyboard Shortcut.
There is no global key to cancel a recording. Click Cancel recording on the on-screen widget instead.
Tray or menu bar: you can also click the Contextli icon and choose Start Recording or Copy Last Transcript.

Main hotkey: Settings > General > Keyboard Shortcut. See Change your recording hotkey.
A context’s hotkey: Contexts, edit the context, then Global hotkey.

If a shortcut does nothing, another app may be using it. See The hotkey does nothing when I press it.
