What should I purchase for a Truefox layout of Whitefox keyboard?



you can cover truefox usingbase + 60% (Using 1.75 Ctrl for Right Shift)base + atomic + 60% (Using 1.75 Ctrl for Right Shift)base + atomic + 60% + WKL (Using 1.75 Shift for Right Shift)and cover the remaining 1u caps with whats available in the set. atomic set had the most compatible 1u they had delete,pgup,pgdn,etc but still lack 1u end,homebut theres so many variety 1u like raise,lower to replace home,end (in atomic set) so its maybe not a problem at all and you can fully programmable truefox layoutor maybe you can even use 1u novelty for it
