Creating a task from a comment
One of the most common ways of creating a task to create it from a comment on a document.
Make a comment by selecting some text and clicking the speech bubble on the right-hand side of the page, writing the comment, and clicking 'Comment'.
Create a task by selecting 'Create task' from the drop-down in the top-right corner of the comment.
The task itself will have a preview of the part of the document where the comment was made.
