Bernat Blanket pattern codes

I have just purchased Worsted Wool from Bernat for a rainbow blanket and the first code on the patterns says:
1st row: Kfb. K1, 3 sts. Beg Stripe Pat and cont as follows:
2nd row: (RS) K1, (M1, K1) twice, 5 sts.
3rd row knit.
4th row etc.

What does Kfb mean?

I’ve never heard the term codes. :shrug:

Anyway, KFB means “knit front and back”. It’s an increase. Click on videos at the top of the page, then increases. Half way down on the list on the left out says KFB.
