The help system uses an adapter to display online documentation in a web browser you already have installed on your system. If you have more than one supported adapter and browser, you can select which adapter you want the help system to use. To change the web browser adapter setting:
If your system does not have any of the supported browser adapters installed, you may need to select Custom browser in the Preferences, and specify a path to the browser program that launches your browser. If the program is available on your system path, you may specify only the program name. If the program does not accept URL as its last parameter, you may use %1 string to denote the position of the URL parameter in the command.
