Track action items in your notes by tagging them as to-do items. Then easily manage that list by reviewing all of your tags on the Tags Summary pane.
Take notes by typing text on a OneNote page.
Select the text that you want to mark as a to-do item, click the Home tab, then click To Do Tag. Each selected item now has a check box next to it.
To find all tags, on the Home tab, click Find Tags.
As you complete items, click the box next to each tag to indicate that you are done.
