Add the topic just before the end of your meta information section using the <otherfront> element as follows:
<otherfront id=id><head> Topic Title Body of topic.
The ID parameter and <head> tag are required.
You can add as many <otherfront> topics as you want. They may be in any order, but they must be the last topics in the <metainfo> ... <\metainfo> section.
This partial help volume shows how a general topic is added to the meta information section. The title of the topic is Pop-up! and the ID of the topic is my-popup-topic.
<metainfo> <title> My Help <copyright> This is My Help, Version 1.0. © 1995. . . . <otherfront id=my-popup-topic> <head> Pop-up! This is a pop-up topic, displayed via a definition link somewhere in my help volume. <\metainfo> <hometopic> Welcome to My Help . . .
Presumably, within some other topic in the help volume, there is a definition link to display this topic.
The link might look like the following:
Here's a sample of a pop-up <link my-popup-topic Definition> definition link<\link>.
The words definition link become the active hyperlink and are displayed with a dashed underline. Selecting the link displays the Pop-up! topic in a quick help dialog box.
