Pages

Update or revert a paragraph style in Pages on Mac
A paragraph style gets an override when you change the appearance of text (its color or size, for example) that uses the paragraph style. An override is indicated by an asterisk (*), or an asterisk and an Update button, next to the style name in the Paragraph Styles pop-up menu. To deal with an override, you can do one of the following:
Ignore it: Leave the override in place, and keep the edits you made to your text.
Update the paragraph style to incorporate the overrides: If you update the paragraph style, all text in your document that uses the style is also updated.
Remove the override: Revert your text to its original appearance and leave the paragraph style unchanged.
Note: For information on updating list styles, see Format lists.
