Let you set up, add, modify, use and delete stylesheets for your current document. Stylesheets are preset type and formatting specs you can apply to selected text or text typed after an insertion point. You can create several stylesheets to handle the different elements in your design-different levels of heads, footers, body text, or display type. Stylesheets speed up formatting-you can apply a stylesheet to the entire document at once and ensure type spec consistency throughout.
You can modify stylesheets if your design specs change, and you can also import stylesheets created in another document.
Whenever you manually apply type specs to selected text with a style applied, you must remove the stylesheet first. You can get around this, when first creating the stylesheet, by defining the elements of the style you think you might want to modify as None in the Style Specifications dialog box. That way you can use the speed and accuracy of stylesheets, but keep the flexibility of manually applying type specs as needed.
When you choose Styles, the Styles dialog box appears with a scrolling list of the stylesheets you have defined in the current document.

• New creates a new stylesheet. The Style Specifications dialog box appears. If any text was selected, its type specs are displayed, where consistent. With an insertion point in a text block, the dialog box shows the type specs of the preceding text character. Type the name for the new stylesheet in the Name box and select the options you want for the stylesheet. Select options by pressing the indicator or box to display the choices. To select Type Styles options, click the box you want, and for Color, Tabs, Indents, Horizontal Spacing, and Vertical Spacing press the appropriate button for an additional dialog box.

Some style options show the option None. This can be useful when you want to use a stylesheet to format many characteristics of the text in your document, but keeping the ability to change one or two characteristics without removing the stylesheet. When you click OK to save the stylesheet its name is added to the list in the Styles window.
To use keyboard shortcuts when applying styles, append a slash and a single letter to your stylesheet. For example, if you name your stylesheet 'Body Text/b', apply the style to selected text by typing Command-H-b.

• Modify changes an existing stylesheet from the list in the Styles dialog box. The Style Specifications dialog box displays the current stylesheet and type and format specs of the stylesheet. Change the stylesheet name, type and format specs, or keyboard shortcut for the stylesheet and click OK. Any text you formatted with the stylesheet is automatically updated with the new options. Click Cancel to restore the original stylesheet.

• Apply formats selected text or text typed after an insertion point with the selected style.
  Import lets you import a stylesheet from another RSG document. Click Import: a directory dialog box appears. Double-click the document which contains the stylesheet you want. Its stylesheets are added to the list in the Styles dialog box. Imported stylesheets with the same name as existing stylesheets have '.1' appended to their name. You can modify, apply, duplicate, or delete imported stylesheets just as you would with created stylesheets.

• Duplicate makes a copy of a stylesheet. It's often easier to modify an existing stylesheet than to create one from scratch. Select the stylesheet to be modified and click Duplicate. This creates a duplicate stylesheet with '.1' added to the original name. You can now select the copy and modify it.

• Delete removes a stylesheet from the document. Select the stylesheet from the list in the Styles dialog box and click Delete. Any text you formatted with the deleted stylesheet retains its formatting.

• Done closes the Styles dialog box.
