P1 yo ktbl help

I am knitting a pattern that calls for p1 yo knit through back loop in next stitch. Can anyone help me with that. How do you do all that in the next stitich?

It helps if you don’t knit tight. It’s like doing a purl front, knit back increase, but you take the yarn over the needle instead of between then tips. So purl into the st as usual, but leave it on the needle, lay the yarn over the right needle and knit into the back loop of the stitch.

Thanks so much. I think I got it
