A previous posting mentioned Beagle Brothers!
Gads, that brings back memories.
Friends had an Apple ][+ and the Beagle Brothers printed FUNNY
yet immensely useful things (mostly tips if I recall)!

In Jr. high school, we had programmable calculators
about the sizeof typewriters.  CompuCorp 024 (?)
There were many more functions than keys, so by pressing 2 keys
at the same time, the binary codes for the keys would combine!
The 8 bit code for the key showed on the neon indicators!

d/k key grooves vs f/j key bumps:
I think it was the AT&T UnixPC/3b1 that had grooves along the d & k keys
from top to bottom which were VERY easy to feel and COMFORTABLE!

Now that's it brought to my attention, I'm rather ashamed of HP's
design of the kybd I'm using now.  The little bumps on the
f/k keys are so low on the key to be un-noticable most of the time.
No wonder my fingers keep slipping around.

I agree that making the d & k keys different are better
- the middle fingers stays on the key a lot more then the index
fingers which must handle heys to the side too
- my middle finger's more touch sensitive then my index finger
since it's not used so much in picking things up.
- consistent with the calculator / adding machine / cash register
distinctive '5' key to guide your middle finger there.
