# Comment on or react to a check-in

Reply to a check-in with a comment, or react with an emoji.

Comments and reactions let you respond to an update without changing it. Anyone who can see the goal can do both.

## Comment on a check-in {#steps}

1. On the goal page, open the Check-ins tab.
2. Under the newest check-in, type in **Write a comment...**. For an older one, click **Reply** first. Type @ to mention a teammate, who gets a notification.
3. Press Enter to post. Shift+Enter adds a new line.

## React to a check-in {#react}

1. Click the smiley icon under the check-in. To react to a comment, hover the comment and click its smiley.
2. Pick an emoji.

The emoji shows under the check-in with a count, and the author gets a notification.

## Delete your comment {#delete}

Only the person who wrote a comment can delete it, and it can't be undone.

1. Hover your comment and click **...**.
2. Choose **Delete comment** and confirm.

The comment leaves the thread, along with its reactions.
