Object Width Box  
    The Object Width Box consists of a text box that allows you to 
change the width of an active object. 
     When any item except for a line is active, the value from the box
 represents the width of the item.
    When the line is active, the value from this box means the length of
 the line. 
    To change the width of an item:  Click on Object Width Box. When
 the text insertion point appears enter the desired value in it.  The
 measurement units are those specified through the Ruler Settings
 menu entry (Edit Menu) or directly by clicking on the lines
 intersection in the left top corner of the document window  while the
 Option key is pressed down. When rulers have different settings, the  
units are Inches.
    With the Zoom Tool selected, the value in the box means the Zoom
 increment  percentage.
