Kfb?

Does this mean Knit through front and back? If so, how does one do that??
It is part of setting up a cable row as follows:
[I]Set-up Row[/I] [WS]: P2, k1, p2, kfb, p2, k1, p2.

I have never seen that before…ideas, help…anyone? Much THANKS

nevermind…i found it, it’s an increase. I didn’t know that!
