FrameMaker indexing using a conditional tag
I am updating a FrameMaker book in which a previous author used an indexing technique I haven't encountered before.
There are conventional markers of type "Index", but these are replicated as text with a conditional tag called "Index" applied to it. The markers use this syntax:
.i.[topic]:[sub-topic];
How do you turn these conditional text markers into an index, and why might an author use this approach?
Thanks in advance for any insights!
