The world of computer keyboards is… a little confusing. I have a Keychron K2 75% (non-backlight, brown switches) that I picked up a few years ago. I really like it. In fact I bought two of them – one for the office and one for home. But now I just work at home. So, I have a backup! I wouldn’t mind an alternative set of keycaps. But I have no idea what will work and what won’t. I’m guessing any OEM set? If anyone knows, send me an email. Thanks.
