The Glossary Merge menu item of the Glossary Menu lets you combine the abbreviations contained in several glossaries to form a new glossary. Merging creates a new glossary combining all entries from the glossaries you select.
When merging glossaries, phrases of the constituent glossaries appear in the order set in the merge dialog. Consequently, after typing two letters, the Phrase Advisory shows matching phrases of the first glossary before those of the second, and so on. Any duplicate entries in a merged glossary are discarded upon loading.
