The Help window for this Extension Pack has three tabs for accessing information:
The Contents tab gives you access to a Table of Contents which is useful when you need an overview of topics available and a guide through them.
The Index tab directs you to specific topics you request. Use the Index if you know the topic you are looking for.
The Search tab searches the entire help system for a word or phrase you request. Full-text searching is useful when you are looking for a certain word or phrase, rather than a topic.
When you double-click on a topic, it displays in the right-hand side of the window.
