Mechvibes hotkeys, where settings are saved on Windows, macOS and Linux, and troubleshooting for common problems.

## Hotkeys

Shortcuts that work from any app.

- **Ctrl+Alt+M** — mute or unmute all sounds, from any app. The tray icon shows when sounds are off.

## Where Settings Are Saved

The folder that keeps your settings and packs.

Mechvibes keeps your settings and added packs in one folder, which survives updates and reinstalls:

- Windows: `%APPDATA%\Mechvibes`
- Linux: `~/.local/share/mechvibes`
- macOS: `~/Library/Application Support/Mechvibes`
