Cool !
Btw I think I found a non-disruptive way of entering one-step complex numbers, à la 35S, like I mentioned before.
While in number entry mode, there are two keys that are forbidden to type twice in a row: "." and "E". So on the second keypress, "." could be changed to "i" and "E" to "theta", thus allowing complex entry without altering 42S normal behaviour, nor changing the skin. This also could be used in equation mode, to solve complex values (and allowing complex equation variables) symbolically when possible, as discussed earlier.

What do you think ?

Cheers

On the HP32SII pressing 1..2 enters 1/2. What if we ever wanted to introduce a fraction mode? ;-)
