A:Answer Am using it with Samsung 50HU8550 Smart TV. Right click on Mouse pad brings Tools where you can select Smart Hub, Search, Input Source, OnScreen remote, Power Off. Once you select Smart hub then you can select app using arrow keys and hit enter to open the application.
The keyboard can't be used inside apps (YouTube, Netflix) to type. I use Search option to search videos which lists videos of YouTube, etc.
