Index file keywords

Index file keywords are keywords that are saved in the index file (.HHK) and not in individual HTML topics. The Index Designer identifies index file keywords with a key icon .

Advantages of index file keywords

Limitations of index file keywords

Notes:

  • If you add a keyword to the index more than once, using different combinations of letter cases (upper-case and lower-case), the Index Designer adds the keywords as a single entry, based on the capitalization conventions used for the first entry of the keyword. For example, if you add "Newspaper" the first time and "newspaper" the second time, the index uses "Newspaper" whenever you add this keyword to other topics in the project.

  • The Index Designer displays keywords that are not referenced by topics in bold.

  • If the index includes index file keywords and topic keywords that are identical, the keywords are merged when you compile and are displayed as one keyword from the Index tab (even though they are displayed as two separate keywords in the Index Designer).

  • When you convert a WinHelp project file (.HPJ ) into an HTML Help project file (.MPJ), the keywords in the WinHelp topics are saved as keywords in the index file.
