External documentation makes it possible to get additional information for the symbols at caret. In contrast to the quick documentation, this feature shows the documentation in an external browser, which helps study the symbol in more detail, navigate to related symbols, and retain the information for further reference.
External documentation becomes available for viewing when properly configured in the module structure. For example, in the module paths, you can add a path to a JavaDoc file, or a link to documentation; or specify documentation URL for a library.
