K1,p1,k1 all into next stitch. How?

I am finishing a wrap around sweater that has lace edging on the sleeves and bottom edge. The directions for the first row, after casting on 8 stitches are as follows: k2, *yrn, p2tog [k2,p2,k2] all into next stitch, repeat from * to end. For the life of me I can’t figure out how to [k2,p2,k2] into the next stitch. Does anyone know how to do that?
