From the right-click menu, select Smart Index Topic. The Smart Index Wizard dialog opens.
Select the search criteria.
Select where you want to look for keywords.
To capitalize the first letter of the keyword or keyword phrase, select Capitalize all new keywords. (The Smart Index Wizard does not use upper-case with existing keywords that are not capitalized.)
Click Finish. The Smart Index Wizard scans the topic and displays a list of keywords.
Select the keywords.
