The fundamental Cocoa class for dealing with styled text is the
attributed string.  Take a look at the documentation for
NSAttributedString, NSMutableAttributedString, and NSTextStorage.  Note
that NSAttributedString itself is defined in Foundation, but most of
the useful attributes are defined in the AppKit, in the AppKit header
NSAttributedString.h, so you will need to look at both Foundation and
AppKit documentation.
