KeyHH is a program that augments HTML Help, the help development environment that Microsoft has created for its HTML-based online help systems and electronic books. KeyHH can be used in addition to or as a complete replacement for HH.EXE. KeyHH provides all of the functionality of HH.EXE, offers solutions for some known bugs in HTML Help, and provides additional functionality as well.
KeyHH helps you to resolve these problems with HH.EXE:
You can use KeyHH to create a standalone HTML Help window. This window remains open until the user closes it. Once this window is created, you can open new topics in the window without creating a new window, just as you can with WinHelp. You can use this functionality from an HTML Help window, a program, or a WinHelp file.
Although you can easily link from an HTML Help (.chm) file to a WinHelp (.hlp) topic, the opposite is more difficult. KeyHH is designed to help you to open a .chm file from a WinHelp topic. This feature is especially useful if you're creating hybrid (mixed WinHelp and HTML Help) documentation sets. For example, suppose you decided that you want to use WinHelp topics for What's This? help, since WinHelp popup topics are more feature-rich than HTML Help popups. However, you also want to link from the What's This? help topics to a more complete explanation in a .chm file. KeyHH allows you to do this without creating multiple HTML Help windows.
A common way of linking topics in a help system is through keyword and associative links--KLinks and ALinks, in WinHelp terminology. Both HTML Help and KeyHH support this linking capability. However, KeyHH also allows you to open the new topics in a window that is already open. In addition, KeyHH allows you to use ALinks and KLinks in ways that HH.EXE doesn't support. For example, you can:
HTML Help 1.1 requires you to open a mapped topic in the default window set up in the project. (Mapped topics allow programmers to open a topic in an HTML Help window without having to know the URL. Instead, all they need to know is the id you have mapped to the topic.) HTML Help 1.1 ignores a window type associated with a mapped topic and attempts to open the topic in the default window in your project. If you don't specify a default window, HTML Help attempts to create a default window but doesn't always do a good job. Using KeyHH, you can open a mapped HTML Help topic in any window that you have set up in your project. This doesn't have to be the default window.
If you're using HTML Help 1.2 or later, you don't need to worry about this problem.
KeyHH is free. You may download it and install it on as many machines as you want for no charge. But first, let's get the legal stuff out of the way:

Whew. Okay, the download file is about 49K. You must have either Internet Explorer 4, Windows 98 or Windows 2000 installed or the setup program won't run -- but you can download it with whatever browser you want. When you click the download link, you can either save it to disk and run it later, or just open it and have it run immediately.
