You use the asterisk (*) to insert build tags as footnotes. When you assign a build tag footnote to a topic, the Help compiler includes or excludes the topic according to information specified in the BUILD option and [BUILDTAGS] section of the Help project file. For more information about the BUILD option and the [BUILDTAGS] section, see Chapter 16, “The Help Project File.”
To assign a build tag to a topic
1.1.Position the cursor at the beginning of the topic text, so that it appears before all other footnotes for that topic.
2.2.From the Insert menu, choose Footnote.
3.3.Type an asterisk as the custom footnote mark, and then choose OK.
A superscript asterisk ( * ) appears next to the heading, and the cursor moves to the footnote window.
4.4.Type the build tag name to the right of the asterisk in the footnote window.
Use only a single space between the asterisk and the build tag name. For example:
* test_build
Figure 6.14 shows this footnote window.
