Hi pickbe,
One of the easiest ways to do this is to use a shortcut
control. That will open the remote topic in its own help viewer
(that's sort of a popup/secondary window). If this is what you'd
like to do paste the following in the true code, where you want a
button link. Edit the names to fit your .chm name and topic and
button text.
