On a Congo Kid the softkeys are physical keys that are labelled on the LCD, so there's no general need to duplicate them on the external screens.
If you'd like quicker access to some or all of them in some other arrangement, you can create a Magic Sheet containing your own custom set of softkeys.
My question might not be accurate. I´m looking for a way to remove softkeys area appearing on external screen 2 in case I don´t need them and I would preffer to use a screen space a different way.
thanks
