Apparently all the registers are available as they are in the WP34s.
I know there was discussion about reducing the number of registers to 10 to save keystrokes (I personally don't think this is necessary) , but what about the registers X, Y, Z, T, A, B, C, D, I, J, K, and L?

Most of them don't seem to make sense anymore for a non programmable calculator.
The only one that really makes sense is L, but wouldn't it be nicer to have a LastX key for this, maybe instead of "FILL"l?

The special registers can be addressed in the same way as on the WP34s. However it is a bit odd to find that "ENTER" puts the WP31S into alpha mode without mentioning alpha mode on the key.
While we are at it, what are the alpha labels used for on the WP31S anyway? Maybe using registers A to Z (as on the HP32S) and a dedicated LastX would be an option?
That would save keystrokes as well but preserve more then 10 registers for general use.
