### Using interval and range variables
You can use some global built-in variables in query variables; `$__interval`, `$__interval_ms`, `$__range`, `$__range_s` and `$__range_ms`. For more information, refer to [Global built-in variables]({{< relref "../variables/variable-types/global-variables.md" >}}).
## Annotations
You can use any non-metric Loki query as a source for [annotations]({{< relref "../dashboards/annotations" >}}). Log content will be used as annotation text and your log stream labels as tags, so there is no need for additional mapping.
