The DISH 50.0 Voice Command Remote control adds a microphone for handy voice search and channel changing, and replaces the four-way button pad with a touchpad. The four-direction navigation pad and Select button have been replaced by a simple clickable trackpad that serves the same purpose. Voice search is easy to use and works nearly instantly. Just hold the Microphone button down and speak into the remote, then release the button. If you say the name of a network, your Hopper or Joey will automatically change the channel to it
