Solution 1Recommended

Access 100% Zoom via the Floating Menu

Since customizing the floating toolbar isn't supported, you can manually access the 100% zoom feature through the existing menu structure in full-screen mode.

While you cannot add a dedicated zoom button to the primary floating toolbar, the zoom function remains accessible within a couple of clicks.

1
Enter Full-Screen Mode

Click the diagonal double-arrow icon in the top right corner of OneNote to enter full-screen mode.

2
Open the More Options Menu

Locate the floating toolbar at the top of the screen and click on the three-dot menu (...) to reveal additional tabs.

3
Navigate to the View Tab

Click on the 'View' tab from the expanded ribbon menu.

4
Select 100% Zoom

Click the '100%' option in the Zoom section to instantly reset your page view to its default scale.

Limitation: OneNote does not currently provide built-in options to customize this toolbar, hide the page sidebar, or create a custom keyboard shortcut for this zoom action.
