Style Sheet Box 
    It includes both a pull-down menu and a text box that allows you to 
 change the style of the current paragraph.  
 The Style Sheets Box displays the style sheet that is currently in 
 effect. If a range of paragraphs is selected that contains different style 
 sheets,  the box is empty. 
   The style sheets shown in the Style Sheets pop-up are those that
 have been defined for the active document through the  Style Sheets
 menu entry (Edit menu).
