comments and reactions on a Linear issue


All users with access to an issue can post comments and threaded replies. React with emoji on the issue itself, or on individual comments or threads.


Post a comment

Comment on an issue by clicking into the "Leave a comment…" text box at the bottom of any issue you are viewing. While issue descriptions are instantly visible and saved automatically, you will need to click the Comment button or CMD/CTRL ENTER to post the comment to the issue.

Attach files to a comment using the paperclip icon, CMD/CTRL SHIFT A or drag and drop.

If you navigate away from the issue before posting your comment, the comment will be saved as a draft locally until you navigate back to the issue and post it.

Emoji react to issues and comments

You can leave an emoji reaction on an issue or a comment by clicking the "Add reaction" icon visible at the bottom of any issue or when hovering a comment.

All official Unicode emojis are available by default. Custom emojis can be uploaded individually (JPG, GIF, and PNG formats are supported) or imported in bulk from your Slack workspace via the Emoji settings page.

Comment threads

Thread comment on Linear issue

To respond to a specific comment, create a thread:

  2. Click on the arrow icon in the top right to start a comment thread.

If a thread already exists, click into the text box at the bottom of this comment thread and start crafting your response. Send threads as you would a regular comment

Resolve threads

Resolving threads visually clarifies when a question has been answered, or when a decision is made. This is particularly useful in longer threads to clearly identify the resolution made.

Mark a thread as resolved through the overflow menu on the root message. To showcase a specific resolution, resolve a thread from a particular reply to expose that reply specifically.
