Up and Down Buttons in ALV Grid

Hi,

If you open the Sorting Screen of an ALV Grid, you can select Columns you want to see and you can rearange them by clicking this Up and Down Buttons. Are these up and down buttons Standard or are they only available in this Sorting Screen? Because i also want to allow the user to sort entries in an own ALV Grid by rearranging the entries with Up and Down buttons. Do i have to add them by my own or is there a standard feature. I saw that there is an Move Row Function, but i did not found any documentation on that.

Thanks,
