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.
