Glossary terms can appear in bubble text, Introduction/End frame bubble text, and web page text.
When a glossary term appears multiple times in one location, only the first occurrence is hyperlinked after you perform the Update Glossary Links command. You can, however, select the Every Occurrence Of The Term option to have a glossary term hyperlinked whenever it appears in custom bubble text, Introduction/End frames, or web pages, regardless of the number of times the term appears.
