Hi, ecoulyn,
You need to make a topic file like the one below the target
of the Jump button.
The onLoad function on the Body start-tag causes the Related
Topics command to fire when the topic file is loaded in the topic
pane. When specifying the file name of the topic to display in the
secondary window, you must always prepend it with the name of your
.chm file, followed by "::/". Otherwise, an error message appears
when the Jump button is clicked.
