A digital version of the handheld remote, inclusive of all buttons and functions is represented in the app and works simply by touching the button on the device screen that you wish to use.
Also, a simplified version of the remote control interface is available in the app. The simplified remote menu supports the most basic controls (play, stop, FF, RW, pause, etc) and is good for those who don't need all of the buttons present on the full remote interface and simply wish to issue basic commands. It's also great for those who may find the full remote/ remote interface too complex.
