What you need is a keyboard that can be reprogrammed...

So first, I assume you know the 65% layout right?

If not, you can always map the right mod cluster to become arrow keys on a 60%. How often do you REALLY NEED right Alt, right Ctrl, right Shift and Menu key? Not for me, so on my 60% they become the arrow keys

Then I map the FN key to Caps Lock, I can access most functions with my left hand, plus you can reduce the size + weight of your keyboard
