What is the command produced when long-pressing the OK button on the Roku remote?
The recently updated Spectrum app uses a long press of the Roku remote OK button to enable filtering of channel listings. I would like to know the command the long press initiates so that I can try to mimic it on my Harmony remote.
This is the first I've ever heard of a long press on the OK button doing anything other than performing the OK function. It's possible the remote isn't sending anything different than the OK function, but by detecting the long press doing something different in its programing. If your Roku remote using IR, you might be able to detect any change in the actual command issued by the remote using the learning function of your Harmony remote. But if your Roku uses a WiFi Direct remote, that won't work.
I just did a quick scan of the Roku developer's documentation site, and couldn't find anything about long press support. So it might be just as I supposed at the beginning.
