Change a shortcut
- Open Settings → Keyboard Shortcuts.
- Click Record next to the action, then press the new key chord. Press Escape to cancel.
- Click the reset arrow next to any action to go back to its default, or Reset all shortcuts to restore every default.
Chat, workspace, application, and kill switch shortcuts can be rebound. Send message, Find in chat, Stop current run, Open Mode, Toggle voice input, Approve pending tool, and Quit are fixed. Settings warns you when two actions share the same chord, or when another app already uses your kill switch chord.
