# Working with custom entity types
The entity types list includes any custom entity types that are active for the dataset. From the **Entity settings** page, you can enable and disable custom entity types.
You can also update the configuration of a regex-based custom entity type, and go to the details page for a model-based custom entity type.
## Enabling and disabling custom entity types

Note that any changes to the custom entity type settings affect all of the datasets that use the custom entity type.
For information on how to configure a custom entity type, go to [#custom-entity-type-config](https://docs.tonic.ai/textual/entity-types/entity-types-custom#custom-entity-type-config "mention").
## Viewing the details for a model-based custom entity type

* Edit any custom entity type
{% endhint %}
For a model-based custom entity type, to display the details for the entity type, click the settings icon.
Textual displays the entity type details in a new browser tab.
## Running a new scan to reflect custom entity type changes
When you enable, disable, or edit custom entity types, the changes do not take effect until you run a new scan on each file.
Textual marks each file as requiring a rescan, and displays a prompt to rescan all of the files.
