User Function Key to cycle Number Format

[rgallier]

I have not made it to the point that I understand programming on the HP Prime. This is a primarily feasibility question as to if it is possible to create a user program that would:

(1) Cycle through several number formats (Standard, Scientific, Engineering, & Floating)

(2) If not (1) then swap between two formats (Engineering & Floating) *preferred*.

(3) Then assign the program to the [Shift][User][EEX] keystroke sequence *preferred*.

(4) If not (3) then assign to a softkey only visible after the [Shift][User] sequence.
