A new style or group appears in the Styles panel, with the same name followed by “copy.” If you duplicated a group of styles, the style names within the new group remain the same.
You can also duplicate styles by copying them to another group.
You can organize styles by grouping them into separate folders in the Character Styles, Paragraph Styles, Object Styles, Table Styles, and Cell Styles panels. You can even nest groups within groups. Styles do not need to be in a group; you can add them to a group or to the root level of the panel.
To create the group at the root level, deselect all styles.
To create a group within a group, select and open a group.
To include existing styles in the group, select the styles.
When you copy a style to a different group, the styles are not linked. Even though they have the same name, editing one style does not change the attributes of the other style.
If the group already contains style names identical to those being copied, incoming styles are renamed.
Deleting a style group deletes the group and everything inside it, including styles and other groups.
If you want to use the same replacement style for all styles, select Apply To All.
If you cancel the replacement of any style, the group is not deleted. You can recover deleted styles by choosing Edit > Undo Delete Styles.
By default, styles you create appear at the bottom of the style group or panel.
