Set your author name and color in Keynote for iCloud
You can choose the color used for your comments and for the cursor that’s shown when you’re editing a shared presentation.
You can also change the name shown in comments.
Set your color
Go to Keynote for iCloud, then open a presentation.
Click
in the toolbar, then choose Preferences.In the Author Settings section, click a color.
The color you choose is used for your comment bubbles, and for the editing cursor and dot beside your initials in the participant list in shared presentations.
Colors used in any presentations that are currently closed are not affected by the new color choice.
Click Done.
Set your author name
Go to Keynote for iCloud, then open a presentation.
Click
in the toolbar, then choose Preferences.In the Author Settings section, type a name in the name field.
The name doesn’t apply to presentations that are shared with others. For shared presentations, the name that appears in comments and in the participant list is the name you use to sign in to your Apple Account. To change the name (without changing your Apple Account), visit the Apple Account website. After you sign in, click Edit to the right of your account information, make your changes, then click Done.
If you stop sharing the presentation, the author name reverts to the name shown in Keynote for iCloud preferences.
In shared presentations where you’re not the owner, you can set the name in the participant list only if the presentation’s access is set to “Anyone with the link” and you’re not signed in to your Apple Account; in this case, the name you enter when you join the presentation appears in the list.
Important: If you change the name used with your Apple Account, the name appears in all apps and other locations where you’re signed in to your Apple Account.
Click Done.
New and existing comments are updated to reflect the new name.
