Question on pattern Tampa Vest by Julie Gaddy

I am knitting the Tampa Vest designed by Julie Gaddy and I am puzzled regarding the Chevron Lace pattern. What does “sk2p” mean in row 3? Row 3 is as follows:- K1, yo, sk2p,yo,k2
If it means purl the 2 stitches that you skip, then the yarn is already in front before knitting the 2.

It means “slip 1, k2tog, pass slip stitch over the k2tog” It’s a double decrease.
