Commenting from the editor
You can comment on code fragments and participate in discussions right from your IDE editor.
To leave a code selection comment:
Your comment will be attached to the latest revision. However, you can optionally attach it to an existing review by ticking the corresponding checkbox and specifying the review:
If the code you are commenting on or the file altogether has never been part of the review you're specifying - you might get an error, and your comment will not be posted.
