6. Document reader 
The Document Reader allows you to open files in most supported text-based formats in a Read Only environment with special navigation features. In general, it allows you to read and interact with the elements of these files in a fashion similar to the DAISY Player.
The Document Reader supports the following file types: Txt, RTF, BRL, BRF, Doc, DOCX, PDF, EPUB, XML, HTM and HTML. 
When you launch the Document Reader, it places you in the "Open" dialog. You can activate all the functions of the Document Reader via the Document Reader menu or by using hot keys. The menu in the Document Reader consists of File, Edit, Go To, Read, and Mark. To access these menus, press "Space-M" or "F2".  Select a menu item using "Space-1" or "Space-4" , and press "Enter". Or, you can press "Space-M or "F2" followed by the shortcut for the corresponding menu item.  For example to open the edit menu, press "Space-M" or "F2" to open the menu, and press E.  
The Document Reader also contains various lists and settings dialogs. Use "Space-1" and "Space-4" or the Up and Down scroll keys to navigate menus, settings or file lists. Use "Space-4-5" and "Space-1-2" or "F3" and "Space-F3" to tab among controls in a dialog. For the purr poses of these instructions, we will generally refer to using "F3" and "Space-F3" or simply "Tab". However, in these instances, "Space-4-5" and "Space-1-2" can also be used. Press "Enter" to execute an item.
