# Comment Reactions

> React to any comment with an emoji instead of writing a reply. Great for quick acknowledgements and feedback.

Comment Reactions lets you add emoji reactions to comments on any task. Click the emoji button on a comment, pick an emoji, and your reaction appears under the comment. Each person can add one of each emoji per comment. The comment's author gets a notification when someone reacts.

***

## Enable Comment Reactions

Comment Reactions is **on by default**. A workspace Owner or Admin can disable it from **Settings → Arca Apps** if the workspace does not want it.
