WinHelp 2000 supports all standard HTML 3.2 features, plus all extensions supported by Microsoft Internet Explorer. Since WinHelp 2000 uses the same HTML Layout Engine as Microsoft Internet Explorer and Microsoft HTML Help, WinHelp 2000 supports all the same features.
WinHelp 2000 fully supports all HTML hyperlinks, for example, here's a link to a local page and here's a link to Blue Sky Software's live web site.
WinHelp 2000 also supports jumps to Help topics and macros. Here's an example of the About macro and here's a link to a WinHelp topic. And here's a link to a WinHelp topic in another Help file (displayed in a secondary window).
