# Mark Comments as Read or Unread

## Mark Comments as Read or Unread

Use `markAsRead()` and `markAsUnread()` to programmatically control read/unread state of comment annotations — useful for custom notification badges, read receipts, or "mark all as read" actions.

**API Methods:**

```tsx theme={null}
const commentElement = client.getCommentElement();

// Mark specific annotations as read
commentElement.markAsRead({
  annotationIds: ['ann-123', 'ann-456'],
});

// Mark specific annotations as unread
commentElement.markAsUnread({
  annotationIds: ['ann-123'],
});
```

**Key details:**

* These methods affect the current user's read state only
* Unread badges on `VeltCommentBubble` (commentCountType="unread") update automatically
* Sidebar unread filters reflect the change in real-time
* Combine with `getUnreadCommentCountOnCurrentDocument()` to build custom unread indicators

**Verification:**

* [ ] Annotation IDs are valid strings
* [ ] Unread badges update after calling markAsRead/markAsUnread
* [ ] Used in combination with unread count subscriptions for UI updates
