Deleting styles
It is not possible to delete AOO’s predefined styles from a document or template, even if they are not in use. However, custom styles can be deleted.
To delete an unwanted style, right-click on it in the Styles and Formatting window and choose Delete. If the style is in use, the message shown in Figure 26 appears.
| If an unwanted style is in use, use Find & Replace to replace it with a substitute style before deleting it. |
If the style is not in use, the message shown in Figure 27 appears.
