There are a few different ways you can provide links to framesets, depending on what topics are targeted to open in frames and how you want users to interact with them. These methods include:
Linking a frameset to a TOC book or page: A book or page in the table of contents can display the frameset in the viewer or browser. The entire frameset can open in a secondary window, independent of the main window.
Targeting a hyperlink to a frame or frameset: A hyperlink in the content of a topic can be targeted to both frames and framesets.
