Navigator implements PDF features for all formats (with some
limitations in ConTeXt) with PDFTeX, LuaTeX and XeTeX (i.e.
xdvipdfmx). Features include: Customizable outlines (i.e.
bookmarks); Anchors; Links and actions (e.g. JavaScript or user-
defined PDF actions); File embedding (not in ConTeXt); Document
information and PDF viewer's display (not in ConTeXt); and
Commands to create and use raw PDF objects. Navigator requires
texapi and yax, both version at least 1.03.
