do the different spacebar widths also come with different mounts physically or could in theory I had bought the keychron barebone and [from a full keycaps kit] used a 8-width spacebar instead of 'default' 6.5-width spacebar on it basically?
short story: I finally had a look at nearly all northamerica-sold keyboards (thanks to the kbd.news/vendors/ weblist!) tonight while thinking about that minor issue of only wanting to assign three keys out of there being four physically present to the right of the spacebar, then I ran into this one
https://shop.modedesigns.com/pages/eighty which made me wondering if it was unique to that keyboard or I could try do something similar to the keychron on my own hence this particular post right now
and yes I'll had left the keyswitch out of what should had been the fourth button position (and made sure the via software has nothing assigned there as to avoid any kind of hidden gremlin issue)
p.s indeed this would be for macintosh uses, I don't need the add/subtract keys on numpad side much to bother getting worked up about the extra-big add key heh
