# Parameter :: 12. `unset::`

-- **Summary:** Remove a settings key from the target scope file instead of writing a value.
-- **Type:** bool
-- **Default:** false
-- **Commands:** `.config`
-- **Group:** Config Identity

When `unset::1`, `.config key::K` deletes key K from the target scope's settings file rather than reading or writing it. Mutually exclusive with `value::`.

- **Type:** bool (0 or 1)
- **Default:** `false` (0)
- **Validation:** `unset::1` requires `key::` to be present; `unset::1` with `value::` → exit 1

```sh
cm .config key::theme unset::1            # removes "theme" from user settings
cm .config key::theme unset::1 scope::project  # removes "theme" from project settings
cm .config key::theme unset::1 dry::1     # previews removal without changing file
```
