What is KYOK?

I am doing a very difficult pattern and it asks for a '“kyok” which is knit, yarn over and knit 1 all in 1 stitch. I get the “kyo” bit but I cant figure out how to do the last knit in the one stitch. I would appreciate any help!

Knit the st, leave it on the left needle, yo and knit in the stitch again. It’s a little awkward until you do it a coupla times.

it’s a nice useful increase though! I love it.
