All the data PhraseExpander works with are stored in glossaries, which can store Templates and Autocorrects.
The glossary pane displays all the glossaries stored in PhraseExpander
They contain the list of templates and the associated abbreviations. A template is expanded (upon confirmation) when the associated abbreviation is typed. Template glossaries can also contain macros and perform advanced functions like launching applications and websites, requesting additional user inputs and more. See macros.
In Template glossaries, templates can be further organized in groups.
They contain a list of pairs (misspelled text, correction), used to automatically correct your spelling mistakes as you are typing. These types of glossaries are not meant for expanding abbreviations to full sentences, but mainly for correcting typos.
Autocorrects are triggered automatically when you reach the end of a word (or small sentence), upon pressing a separator key (SPACE, ENTER or punctuation marks).
Autocorrects can also be triggered immediately after typing the last letter that composes the autocorrect. This is useful when you want to insert special characters (like accented letters that are not present in your keyboard) within a word.
