Help with pattern

[Jatt]

Hi everyone,

I'm new with knitting and discovered this amazing site to help me.

I have a few questions regarding the first pattern I'd like to realize.

1 - *k2tog, YO, repeat from * to end of round
I understand what k2tog means. I have a problem with YO. Yarn Over. The video shows it as Yarn Over then Knit 1. In my case, am I suppose to knit 2 stitches together, yarn over, then knit 2 stitches together again, yarn over and go on and on till end of the round? Or knit 2 stitches together, yarn over and knit 1 (as in the video), knit 2 stitches together, yarn over and knit 1, on and on till end of round?

2 - What does TURN means in a pattern? I have a section where it says Knit around to 7 stitches before Marker A, wrap next stitch and TURN. Purl across to 7 stitches before Marker B, wrap next stitch and TURN.

3 - what is a kfab? is it the same as k1 f&b or kfb?

Thanks a lot for your help
