KHotKeys under KDE 2.1.1

Has anyone been able to get khotkeys to work under KDE 2.1.1, or even to locate a description of it that explains how to set the hotkeys? (These are keyboard shortcuts for applications.) When I call it from a shell, it merely returns without visibly doing anything. Somewhere in the KDE help it says that you should install it if you want keyboard shortcuts, but there's no explanation of what it takes to activate it or define the shortcuts. Paul Abrahams
