Index Editor For creating the Index for your help project, you should use the Index Editor which can be called by choosing the Index command from the Tools menu or clicking the appropriate button on the Tools toolbar. This topic describes how to create the Index for WinHelp and HTML Help projects. Index in WinHelp The Index in a WinHelp system is based on the values of the topic Keyword properties. This means that to create the Index for a WinHelp project, you need to assign Keywords for those topics, which you wish to see in your Index. Like the table of contents, the Index can have a tree-type structure. You can type Keywords of several help topics in the following format: Common Name:Keyword Name. Also, it is possible to use such a format: Common Name:Common Name,Topic Name. Using one of these formats for keywords will let you move secondary topics at the right. But to edit the WinHelp Index by assigning topics' Keyword properties is inconvenient. Therefore, we recommend to use the Index editor which lists keywords of all the help topics and lets you edit them in a more convenient form. In addition, using the editor, you can build the Index in automatic mode by clicking the appropriate buttons. Index in HTML Help Unlike WinHelp, using the Index Editor to create the Index for your HTML Help project is mandatory because you cannot edit keywords when editing properties of a help topic. In fact, a topic in HTML Help does not have the Keyword property and the Keyword field you see in the Topic Property dialog box shows topic keywords which are taken from the Index created with the Index Editor. Using the Index Editor for creation of the HTML Help Index is simple. Just use the Add, Remove and Edit buttons for adding, removing and editing keywords. Use the arrow buttons to move the selected keyword. Also, use the appropriate buttons to build the Index in automatic mode. Editing A-Keywords Both WinHelp and HTML Help projects support A-Keywords. To edit A-Keywords for several topics can be inconvenient like editing several keywords for creating the Index in WinHelp. Therefore, to edit A-Keywords, you can also use the Index Editor. Just switch the Edit box located at the top of the editor's window to A-Keywords and you will see a table with A-Keywords for all the help topics. So, you can write and edit A-Keywords with the Index Editor as well.
