Next/Previous Links Between Pages
If you have a lot of material and would like to break it up on separate pages, you can add a Next/Previous link at the bottom of each page, allowing readers to move from page to page.
To do this, put all of your pages all together into one sub-folder. Open the folder, click Contents, click Edit, then Settings. The third option is "Enable Next/Previous Navigation: This enables next/previous widget on content items contained in this folder." Click to checkmark the box next to this option. Save. To remove the link, just edit the folder Settings and un-checkmark the box.
