>>yfwd, sl 2 pw, yarn back<<

yfwd is “yarn forward” which is just another name for YO (yarn over). Just bring the yarn forward between the needles.

Sl 2 pw is “slip 2 purl wise” which means slip two stitches from the left needle to the right (unknit). Pw means you slip the right needle into the left two stitches from right to left…as if you were going to purl.

Yarn back just means to move the yarn back between the needles to the back so you can knit.
