When you're reviewing a document with tracked changes (or editing a document yourself), do you ever get distracted by all of the formatting notes?
There's an easy way to turn them off and leave all of the other tracked changes visible, and it works in both Word 2007 and Word 2010. Just go to the Review tab, click Show Markup and uncheck Formatting:
Likewise, you can hide Comments, Ink, Insertions, and Deletions or remove the Markup Area Highlight shading behind where comments and other change notes appear. You can also hide notes from a specific reviewer, though the changes they made will remain unless you reject them.
