Что же лень-то такая: нажать F1 и прочитать о возможностях программы, которую используешь (про "почитать книжку" уже и не говорю).
F1 > "Styles" > "To preserve or remove overrides when applying paragraph styles"
To apply a paragraph style and preserve character styles, but remove overrides, hold down Alt (Windows) or Option (Mac OS) as you click the name of the style in the Paragraph Styles palette.
To apply a paragraph style and remove both character styles and overrides, hold down Alt+Shift (Windows) or Option+Shift (Mac OS) as you click the name of the style in the Paragraph Styles palette.
Right-click (Windows) or Control-click (Mac OS) the style in the Paragraph Styles palette, and then choose an option from the context menu. You can then clear overrides, character styles, or both while applying the style.
F1 > "Styles" > "To clear paragraph style overrides"
Select the text containing the overrides. You can even select multiple paragraphs with different styles.
In the Paragraph Styles palette, do any of the following:
To remove paragraph and character formatting, click the Clear Overrides icon , or choose Clear Overrides from the Paragraph Styles palette.
To remove character overrides but preserve paragraph formatting overrides, hold down Ctrl (Windows) or Command (Mac OS) as you click the Clear Overrides icon.
To remove paragraph-level overrides but preserve character-level overrides, in the Paragraph Styles palette, hold down Shift+Ctrl (Windows) or Shift+Command (Mac OS) as you click the Clear Overrides icon.
Note: When you clear overrides, paragraph-level overrides are removed from the entire paragraph, even if only part of the paragraph is selected. Character-level overrides are removed only from the selection.
Clearing overrides does not remove character style formatting. To remove character style formatting, select the text containing the character style, and then click [None] in the Character Styles palette.
