This Specification example illustrates a multi-command application. It extends the Web Wheel Application's functionality by allowing you to go backward or forward through its list of web links. You associate one (or more) tag with each direction.
Most notably observe the application element, which features two commands. Then notice how the command-id are used in the configuration of the text2integer-mapper block.
Commands are available to applications via the command-id-in pin on an application. We then map the command to an integer, which will influence the cycling direction within the links.
