- On the Home tab, click the Find Tags button, and a pane will open on the right side listing all of your Tags.
- At the bottom of the pane, click Create Summary Page.
It will list all the tags, but it's easy to delete the ones that are not To-do items. And if you select or hover over an item, it displays a "OneNote" 
icon that you can click on to navigate to the page the original item is on. Quick and easy enough for you?
