Ah, okay good to know you’ve seen those. Just wanted to check in case you missed something that suited you perfectly. It sounds like you have a clear image of what your ideal keyboard would be. 👍
Also I have no idea if I’m using the terms right either but I think the roller is the same as the scroll wheel? And rotary encoders would be those dial knobs.
I’m with you on having a trackball on the right half and a scroll wheel on the left, that sounds amazing. 😁
