[34s] keyboard entry puzzle

[nsg]

I had to enter a command

RCL+ [->]Z

and it was not as easy as I thought. Eventually I figured it out, but at my lowest point I considered changing algorithm so it would use RCL+ [->]Y instead (which I had no problem entering).

RCL + ENTER + is the sequence for this. RCL * ENTER * for RCL* T. The entry sequence for stack registers is ENTER then the letter. We allowed a shortcut when things were unambiguous which turned out to be almost everywhere. Marcus added the . . shortcut for X later which is also handy but not applicable for Z or T in this situation.

The alpha layout when through quite a number of iterations and a lot of thought was put into it. The final layout isn't perfect but it was the best we came up with.
