I'd like to use the Roku enhanced voice remote with the following features "Power up your TV, adjust the volume, mute, and control your streaming. Use Roku Voice to quickly search and more, enjoy private listening with connected headphones, and set personal shortcuts for one-touch control." with my 2018 Roku Ultra 4660X with software ver. 9.4.0 build 4183-46. Will this remote work including programming personal shorcuts? Related: what do the 4 blank buttons at the button of this remote do, are they programmable? Thanks.
Sorry, but they are not. Certain IR universal remotes from UEI will give access to a third programmable key, call it 3. Those include the Inteset 422-3 universal and One-For-All urc-7880. Which accept 5 digit codes for individual functions, which are called Advanced Codes or EFC's. So the codes are 1: 00038, 2: 00040, and 3: 00042. Initially you will need the microphone key to speak the voice command you want memorized, then instead of holding down the 1 & 2 keys on the roku ultra remote you press 1,2,or 3 on UEI universal.
