Edit a style

  Open a Styles panel.     Select the style you wish to edit.
  Click the Edit... button on the Styles panel to display the Paragraph Style Definition Panel.     Edit the style and press one of the following buttons
  Cancel cancels any change you made.
  Save Only does not affect the document, but changes the style for subsequent uses of that style.
  Apply Unforced applies the defined attributes to all paragraphs that are based on that style only where local overrides have not been declared. Overrides exist at the attribute level, i.e. for some paragraphs, there may be partial application of the new style information.
  Apply Forced forces all defined attributes into all paragraphs that are based on the style. If local overrides exist for a paragraph, they are discarded.


Only attributes with the Attribute button on (highlighted) are defined as part of the style.
If an attribute is undefined for a style (i.e. the attribute's button is not on) a paragraph will acquire a value for that attribute from its previous style.  For example, create a style called Section with a font size of 24pt, and define body as its Followed By style.  If body does not have the Font attribute on in the Paragraph Style Definition Panel, it will be set to 24pt when it is created after a Section.
If you apply a style to a paragraph and then edit the attributes of the paragraph (either on the ruler or the Paragraph Inspector) those changes override the style definition.  You can remove the local overrides by re-applying the style to the paragraph.
As you edit attributes on the Style Edit Panel, you change the definition of the style.
You can rename a style by selecting the style in the Styles Panel, selecting Edit... to display the Style Edit Panel, typing in a new name, and saving the style.
When you edit an item tagged with a style,  the definition of that style does not change.  The changes you make override the style definition.  If you later apply (or force through the Style Edit Panel) a style to that paragraph, the local override changes are removed.
