You can define customized command keys in your WebFacing application to invoke a Web service, JSP, or html page. These command keys override the existing function keys and can connect to a Web application URI or an external URL. You might have already defined a JSP or service using a Web diagram, in which case, you can use command key actions to invoke that object or service.
