# Configuring Annotation Tagging

Annotation tags are useful in various situations. For example, you could set up tags to track the status of annotations or to identify the type of review they relate to (Legal, Medical, etc.). These tags can then help users to find, filter, reply to, and track annotations.

## How to Enable Tagging

 To enable tagging, select the **Enable annotation tagging** checkbox in **Admin > Settings > General Settings**.

## How to Configure Available Tags

Only users with the _Viewer Administration: Manage Tags_ permission can configure tags. Available tags are the same across all document types and lifecycles.

To add or remove tags:
  1. From inside any annotation, click the **Select a tag** field.
  2. Click **Manage tags** to open the _Tags_ dialog.
  3. Optional: Create a new tag by entering the name in the text field and clicking **Add**. Tag names can be up to 49 characters.
  4. Optional: Remove an existing tag by selecting it from the list and clicking **Delete**.
  5. Optional: Modify a tag name by selecting it, clicking **Edit**, and making the change in the text field.
  6. When finished, click **Apply**. The tag changes take effect immediately.
  7. Optional: Modify a tag label by selecting a tag and clicking **Edit**. Existing labels appear in the Edit field and can be modified by selecting the text field, editing the label name as required, and clicking **Add**. The updated tag name is now applied to all instances of that tag throughout Vault, as well as in annotation filters. 

Note that deleting an existing tag removes it from all annotations in which the tag is used.
