Version : √ OneNote Desktop
To flip pages in your notebook without using the page tabs, you may add the Previous Page & Next Page buttons in your Quick Access Toolbar (File>Options>Quick Access Toolbar).
This is a distinctive feature of Docked pages which then becomes available on any normal window !
It allows to stay in Full Page mode, yet having the ability to navigate through your notes, without showing the page tabs (which reduce the space available for note taking).
In addition, you may use the Back & Forward buttons :
The Back button goes to the previous note your where in. This is different than the Previous Page which goes to the previous page in your note’ list. Back may go back to a note stored in another notebook for example.
I recently discovered a video explaining the setting of Quick Access Toolbar. If you are not yet familiar with Quick Access Toolbar in Office programs, it could be worth watching !
* If you want to know more about Docked Pages, where I first noticed those buttons, follow this post Docked pages & Table of Content = a powerful work flow.
Finally, if you are interested in the genesis of OneNote, and the early care of its designers for the navigation issues, I suggest you read this blog post.
