In my opinion the BREAK key does not belong on the main keyboard. I think that this was the main fault with the VT100 keyboard, several times I would make that fatal error of hitting BREAK, when I actually wanted DELETE. The issue of fitting the two keys with different weight springs is a good one on the surface, but many typists tend to use enough force when striking the keys to overcome the differential. The answer is to reduce the chances for error by separating these two crucial keys by a considerable distance. David Cherson

I agree that in placing the BREAK key beside DELETE is a layout mistake which may not be countered by differing spring weights. On the keyboard I'm most accustomed with, BREAK is in the first row at 40 lbs. and DELETE is in the 4th row at 30 lbs. I would disagree with the assertion that ranging the key-weights does not reduce errors in typing. Increased key-weights are normally placed on the peripheral keys, where leverage on the fingers is such that it does make a difference. I know personally that the heavy spring in the BREAK key on my terminal has saved me more than once from accidentally typing it instead of RETURN.
