I have several questions about the keys:

1.
I read in another Q&A that you are producing the keys? Will you have stock replacement keys in the future?
If in the future I would like to replace some keys and buy them from Unicomp, will they look the same or will there be a visual difference?

2.
Can a keyboard with normal right shift key later be modified to have a split right shift key? What would be neccessary to do that?

3.
Can I order single blank keys? How to do that?
