What’s an average British pizza? Domino’s is by far the biggest seller in the UK, followed by Pizza Hut and Papa John’s. I would agree that american pizza is shit tier - especially from chains like these - but why would it be any worse than anywhere else?
I have a similar keyboard to OP. I have a layer with a grid of f-keys on the left and a standard numberpad layout on the right.
Combos like that are fast, simple, and no contorting or excessive stretching required since every f-key is within one key distance of the home row (I regularly use L-Alt+L-Shift+f-key combos)
