Clear row in Arr

I have been getting into using the arr and I have been able to do everything i have wanted to - except CLEAR a row. As I understand from the manual - i highlight the row i want to clear and then push func+clear (play). Copy and paste work as expected but i cant get clear to work for me

Function- Up :slight_smile:

Thank You!

Just curious, what is FUNC+PLAY doing, then ?
