Do you mean one like this one? https://www.amazon.com/Microsoft-B2M-00016-Natural-Ergonomic-Keyboard/dp/B000MQAPPC
I had one like this before but an accident occurred ... my fault XD. It broke and as I work a lot at night I decided to try this with light. I have to admit that I am feeling the difference in the position of the keys ;) but the light helps a lot.
A mix would be perfect but I have not find one still. Lights are more for gaming keyboards and the ergonomic stuff for writting ones ... looks like that is how those who make them think.
Btw, you are welcome (saw your message) :)
