KeyTools is a set of utilities for managing the WinHelp and HTML Help systems on your computer, and for optimizing those help systems for better performance.
The primary focus of the KeyTools utilities is HTML Help, the Microsoft development environment for developing HTML-based help and multimedia titles. Since many people who develop HTML Help systems also often have developed WinHelp systems, KeyTools also includes a few tools for WinHelp development. However, the focus of KeyTools was on HTML Help and HTML-based help utilities.
