After you start a keyword search, a list of suggested keywords for the topic is displayed. From this dialog, you can look up subkeywords, select one, and add it to a keyword.
Note: If you are creating an index automatically, this feature does not apply.
Select the main keyword that will use the subkeyword.
Click Options and select Verb from the menu.
From the list of words, select the one to use as the subkeyword and click OK. The subkeyword is added to the list, underneath its corresponding keyword.
If you need to modify the subkeyword, click Rename, modify the text, and then press ENTER.
