I'm looking for a keyboard that I can customize so that I end up with a dvorak with uk punctuation layout that is generated by the keyboard rather than at the OS end. An obvious contender is the Poker 3. The one problem I have with the idea is the lack of arrow keys (I currently have a HHK P2 which has the same problem and, despite the Fn layer, it is a hassle). Looking at the keyboard, the obvious thing to do would be to reprogram the 4 keys to the right of the space bar as the arrows, with a bit of additional remapping to provide Fn and Pn keys in that layer.
I know Fn and Pn can't be reprogrammed in the base layer, but can they in the others? I have read conflicting reports of this: someone else asks this question on Amazon and the answer in Yes, but other places say No, these keys cannot be reprogrammed. I can see logical reasons why it might not be possible to reprogram them. Can anyone tell me the definitive answer please?
Thanks!
