Open Documentation
The Documentation command opens the Cygnus online documentation in your default web browser, so you can look up how a feature works without leaving what you were doing to search for it.
Open the Documentation
To reach the documentation:
- Click Help → Documentation on the menu bar.
The documentation opens in a browser window, and Cygnus stays open behind it.

Because the command hands off to your default web browser, you need a browser and an internet connection to reach the documentation. If Cygnus cannot launch your browser, it reports the failure in an error message rather than doing nothing.
