The Styles dialog provides options for setting linked styles (contained in external style sheets) and embedded styles (included in individual Help topics).
Styles: Displays a list of default styles such as Normal, Heading 1, etc., as well as any custom styles that you've created for the style sheet or Help topic. You can modify these default styles, create new ones, and duplicate (copy) existing styles.
The symbol next to the style in the Styles list indicates style category:
paragraph
style
character style
Other
To modify a style, select the style you want to change and click Modify. The Modify Style dialog opens.
To create a new style, select the style you want to base the new one on and click New. The New Style dialog opens.
Note: "Other" includes default lists, default font (on Background + Text), and topic background. You can't create these styles, but you can modify them.
Hide inherited styles: When selected, displays only user-defined styles in the Styles list. (To see default styles as well as customized styles in the Styles list, remove the check mark. The default styles are pale gray to distinquish them from the User-defined styles.)
Available in: Determines where the styles will be available (style sheet or topic name).
