You can also enable users to find and view topics by assigning keywords to the topics. You assign a keyword by using the \footnote statement and the letter K as the footnote character. Windows Help collects all keywords in a help file and displays them in its Index tab. Using this tab, a user can select a keyword and view the help topics associated with it. The following example assigns the keyword "Sample Topics" to the current topic:
#{\footnote topic1}
${\footnote My Topic}
K{\footnote Sample Topics}
This is my first topic.
\par
\page
If a keyword begins with the letter K, you must place an extra space before the word. Multiple keywords for a topic are separated by semicolons.
A keyword can be assigned to any number of topics. When the user selects the keyword in the Index tab, Windows Help displays all topics associated with the keyword. The user then picks the one to view.
You can also create alternative keywords for a help file for use with the WinHelp function.
