It's a split keyboard in 4 parts and 101 keys, though i could move the number pad and control pad to outside of the thumb keys if making a 4-piece keyboard is too hard or complicated.
Left thumb gets space, control, and super. Right gets space, hyper (just a 3rd layer), and alt. The keys next to T and N are repeat keys. Above Fn is escape and sleep. Above power is compose.
The control pad has cut, copy, paste, open, select all, save, undo, and redo.
I think that's every key i'll need, especially with a compose key and so much extra space available on the hyper layer.
Is there anything i've forgotten to consider? Anything i should know about split keyboards, or custom shapes in general?
More specific question, are 0.5u switches and caps available anywhere for all my small keys? I could replace most of them with full size keys fairly easily, but the 101st key on the number pad would make the layout asymmetrical.
Personally I do reposition throughout the day, but that is personal preference.
It is more and issue on how you do the connections between parts so everything can speak with everything else.
My commercial split has a master half that I could use standalone, the other half needs that master to function though. I imagine that also applies on a scale and then you run into problems on how to do the matrix without compromising nkey-rollover.
