JD 5k series with new power8 & powerQuad trans options question

[Brown Dog]

Does the buttons on single shifter knob change your 1234 gears ?

OR does that still give you the hi/lo option to have 32spds like my current trans ?

What is the turtle / rabbit on the loader joystick ?

I think this vid that seven gables sent me : answers my question.
