Comments
Use comments to improve and facilitate collaboration on notebooks and reports.
Basic procedure
Add comments in notebooks or reports
The comments feature works on the cell level. You can leave a comment to any specific cell in the notebook or report. Each original comment starts a thread that will contain the initial comment and all respective replies.
Open the notebook or report.
Click the Add comment icon next to the upper-right corner of the cell.
In the comment box, click Add comment. A text field will appear.
In the text field, type your comment.
(Optional) To mention another user, do the following:
Type @. This will open a list of users that you can mention.
Click the user you want to mention. Their user name will appear in the text field for your comment.
(Optional) To mention another user, repeat the steps.
After you finish writing the comment, click the Post button.
Once your comment is added:
A separate thread is created that will contain the original comment and all replies to it. Multiple comments form a stack of threads, all displayed in the same comment box for the respective cell.
If added to a cell in the report, such a comment will be marked with a REPORT label.
In the image below, you can see a comment view with two threads. One of the comments was added in the report and marked accordingly.
Notebook/report owner and users mentioned in the comment are notified via email. If you don't want to get notifications, go to and select the None checkbox.
