I looked around their site previously and didn't see any suggestion that red keys were available, printed or otherwise.
What I really want, is white printed letters, but that would require a custom order of minimum 100 keyboards; nor do very grey keycaps.
In particular, I want the function keys labelled f0–f11, as the BBC Micro curiously numbered the function keys f0–f9, with white lettering on the bright orange keys.
Since I can't order anything remotely like what I want from Unicomp, I need to decide what the closest is that I want. I don't really like blank keys, and I can't have any dark keys, so I don't know.
I hope that I can at least have red LEDs.
