This command detects when a knit stitch changes from one needle bed to the other and creates the necessary transfers for that. It does not work for tucks.
Select an area with front and rear knits and pick the mode “Between rows”. Transfers will be automatically generated to bring those stitches to one side or the other.
The modes “Above to front” and “Above to rear” create a set of transfers at the top of the knit, bringing all the stitches to whichever chosen side (if they are not already there).
