Why the need for a third CTRL key, when the only backspace key is currently in Siberia?

It was a sad day (well, presumably pair of days) when Sun & Apple gave up that fight and moved caps lock into that position.

Also, Apple definitely had the nubbins correct (D and K) and foolishly surrendered that as well: they're easier to notice when they're under the wrong fingers. With them on F and J, if your hand is offset towards the outside you're forced to notice the absence of the nubs.

Speak for yourself. I prefer SHIFT, I have too much muscle memory with CTRL+ZXCV and just pushing down CTRL down with an edge of my palm.
