Not easy. You can harvest double shots from another keyboard. Those are pretty easy to see almost in the dark.Show Image(http://geekhack.org/attachment.php?attachmentid=8302&stc=1&d=1268340079)
And there is a nifty mod on Instructables on how to bring a LED out for lighting. :biggrin1:
I might have some white doubleshot key caps like Ripster has in that photo, PM me if interested.
Actually, I'm still a bit vague on what's what with the doubleshot keys. Are they just made from a thicker material? Do I have to get doubleshots if I want to swap them onto a Filco keyboard?
Check it (http://geekhack.org/showwiki.php?title=All+About+Keys).
Filco and Steelseries keycaps are completely interchangable in any combination, they have the same size, height and slope. Cherry caps fit on both, but they're lower. No problem if you swap a complete set, but mixing them with Filcos/7Gs will look and feel a bit odd.
