Embedded topics enable you to reuse text (either complete topics or selected fragments) and have the option to update all instances of the text throughout the library, simply by updating the content in the embedded topic.
As you work with your content, you'll identify text fragments that can be reused in the library as embedded topics. Simply select the text that you want to reuse, and then use the Create Embedded Topic option to create the new "source" topic and store it in your chosen folder.
Existing topics can quickly be split into a combination of standard text and embedded topics by using this method.
