The online help keyword index is a multi-level list of keywords that are associated with topics.
Navigate the keyword index with single clicks.
To use the keyword index start typing a singular, specific keyword in the search box. This will position you on the alphabetic keyword list. Click a keyword on the list to see all help topics associated with it. When you click one of these help topics, it opens in the right-hand topic pane.
Subkeywords are indented groupings of keywords under a main/parent keyword, making it easier for you to find what you need.
