A "switch" button, (that reverses the contents of the "X" and "Y" 
registers)? A rollDown button (like a shift register through x,y,z and t)?

The RPN ease and beauty is resident in the "enter" key, and the four 
arithmetic operator keys. The switch and Roll keys help, because they do a little 
stack fiddling. But advanced functions are but window dressing. Nice, but 
not the core.

You know this.
