You can access these options from the "Advanced" tab in "HtmlHelp Compiler Options". Each option is described below:-
[Options]
Although Fast-Help manages the HtmlHelp Project file (.hhp file), you may want to add specific options to the Project [Options] section. This is only advised for very experienced html help authors. Whatever you add here will be appended to the [Options] section at compile time.
[Merge Files]
See the section on Merging HtmlHelp files for a full tutorial on using this section.
[Files]
Anything you add here will be appended at the end of the [Files] section during Compile.
[Map]
Anything you add here will be appended at the end of the [Map] section during Compile.
[Alias]
Anything you add here will be appended at the end of the [Alias] section during Compile.
[Text Popups]
Anything you add here will be appended at the end of the [Text Popups] section during Compile.
<HEAD>
This refers to the Html Header section of a Html file. Whatever you add in here will be added to the head section of all the html files saved in Fast-Help during compile. This is very useful if you want to add a specific file such as a CSS or JavaScript file.
