The Pretty Printing section (see screenshots below) enables you to specify how text is displayed in the XML document represented in Authentic View. Although Authentic Desktop does not provide a text view of the XML document, the settings that you choose here will be applied to the raw text of the XML file that you are editing in Authentic View. The setting is for whether you wish to use tabs or spaces for pretty printing.
