Ask HN: Searching for wireless split keyboard due to shoulder injury

Hi all, I’m totally new to mechanical keyboards. I recently suffered an accident to my right shoulder and I will be in a sling for a significant time. My plan is to have a right keyboard on my lap on a pillow, or probably something similar but firmer. Can anybody recommend a wireless split keyboard? Does anybody have experience with this kind of set up? Would the moonlander do the job?

Secondarily I live in London, UK, and I need the keyboard ASAP, as I depend on it to be able to work. Therefore recommendations on where I can buy such a keyboard in the UK would also be appreciated.

But I’m a bit overwhelmed with all the choice
