Whenever you work with other people in a shared notebook, newly added and revised notes by others will be marked on your screen with a vertical color bar and the initials of the author who made the changes. This makes it easy to spot each other’s contributions when collaborating on a project.
You can turn these formatting marks off if they distract you from reading your notes.
Do the following:
In the shared notebook containing author’s formatting marks, click the View tab.
Click Hide Authors to remove the color bars and author initials.
Tip: To turn these marks back on, click the Hide Authors button again.
