The rich text contents of the text view are held in its textStorage. 
This is an object of class NSTextStorage, which is a subclass of
NSMutableAttributedString.  You can deal with it directly, or copy it
into another attributed string.  If you wish to pass it to another
application, or store it in persistent form, you will probably want to
either archive it, or else (more commonly) store it in an external
format such as RTF or RTFD (for text with attachments).  For this
NSTextView provides methods like RTFFromRange: and RTFDFromRange:
(defined on NSText), and the AppKit's NSAttributedString.h header also
defines various methods for reading and writing RTF and RTFD.  You can
take a look at the sources to TextEdit to see some of this in action.
