OneNote gives you the capability to insert a hyperlink to another page within the same OneNote notebook, or even in a different notebook.
Type and select the text you want to serve as your link. For example, “Click here for details.” Use Ctrl+K or click the Insert tab and choose the Link button. Use the “Or pick a location in OneNote” section of the next dialog box to locate the page you want to link to. You can also right-click a page and choose Copy Link to Page and paste it where you’d like to reference it.
