There are 29 note tags in OneNote.
Did you know that you can tag notes as you work in OneNote? If you're in a meeting and have an action item assigned to you, or just want to make sure something doesn't fall through the cracks, tag it as a To Do item, or as Important.
OneNote then helps you find any tagged note by grouping note tags and displaying them in a list.
