Linked notes is a way to link any documents like Word, Power point presentations , to One Note Sections or pages. While in Linked Notes mode, a button with a chain link icon is displayed near the top left corner of the docked notes page. While in a Linked Notes session, you can hover the mouse pointer over individual notes on the page to see which notes are linked to something else.
Hovering the mouse pointer over any of the application icons that may appear on the page will display thumbnail images of any Word documents, PowerPoint presentations, OneNote notes pages, or Internet Explorer Web pages that the notes are linked to. You can click any of these thumbnail images to open their associated files.
