Microsoft Word provides several tools for
document collaboration
. One of these features allows you to
insert comments
into a document and provide suggestions to the document's author without changing the original text.
To insert a comment:
Position your cursor next to the word where you would like to insert a comment.
Select
Insert
Comment
from the main menu. The Reviewing toolbar will appear at the top of the page, and a
comment balloon
will appear in the margin.
