> I think these are the wacky keyboards where they had the "D" and "K" keys marked with a nub to indicate home keys. Drove me crazy enough that I'd deface them by shaving off the original nub and put a "proper" ridge into the f and j keys.

I have these caps on my keyboard and I can confirm this. I think I actually like it since it helps my muscle memory type one way on my laptop and another on my vertical staggered external keyboard. I bought an original for the caps and switches. Almost all the switches had been desoldered and replaced with Alps compatible Matias click switches which weren't even soldered in. Stinks. Could have raised a stink but whatever.
