Given this is now released, I'm happy to report that the third-party control client for the Elgato Streamdeck, called OpenDeck, is now a lot more accessible for #screenReader and keyboard-only users.
These devices have always had a huge #accessibility barrier in that the only way to assign an action to a key was through a drag-and-drop interface. Elgato has been notified about this, but proved ... let's say ... less than ehtusiastic to fix it. So, I did.

While I can't claim 100% accessibility, primarily because that isn't a thing, I can say I made sure everything I could find was labeled, and that there's now a keyboard-only way of associating buttons, knobs, and touch controls with actions, something the official client does not, and probably will not, support.

I'll be making a video on the ViewpointUnseen youtube channel with all the details soon.

@zersiax florian, be honest, do you know telepathy? We talked about that on a Russian-language YouTube stream, and my friend presented Elgato Stream Deck. I said I want this right now, only it's not accessible. So it's you who did that?

@menelion I did see this,yes, I think at the time I concluded it didn't really fit my use cases but it might work for others, I forget what made me dismiss it
