I'm trying to find the 'proper' method to do this basic concept of incrementing a value (in this example) once per key press: Is there a more efficient (using less cpu and/or less code) way to do this? I am also curious why you can't add shift registers to the case structure.

It doesn't get much more efficient than that. The is an increment '+1' primitive in the numeric palette which makes the code look a bit smaller but I suspect the compiler is smart enough to spit out the same thing either way. It is considered better coding style to use an event structure to react to controls rather than polling. That will probably save a little CPU drain, although I see you have a 50ms wait in your polling loop to curtail it being too greedy. Shift registers only make sense on structures that implement a loop-a case does not. You can create shift registers on your outer while loop and wire to that.

Thanks for the additional suggestions. I tried them out and think I understand them all now.
