Yes, ISO, thank you. My interest in non mainstream keyboard is kinda new
I meant "TK" as in compact. Sorry, still new with those terms! No numpad, can probably do without the arrow keys too although I don't mind having them. Just something more compact than your standard full keyboard. But no numpad for sure.
I mentioned Red keys because that's what I got currently and like it. Ive tested brown but I found it super not responsive, really didnt like it. Didn't think it was that different from Red. I don't want black because i heard it's bad if you tend to have rather fragile hands/articulation, which i do have. Interested in testing blue because i don't only play but also type quite a bit, and apparently its pretty good for typing. Seems impossible to find a MX Blue keyboard to test in Geneva though..
Had a look at the website you mentioned, teraset, found some German/Nordic layout indeed, no idea if they can modify it to offer a Swiss layout or if i'd have to change it all myself (which is a bit of a hassle for me since i'd have no idea what to pick).
