Help with directions

Hello, I am new to the boards and pretty new to knitting. I am starting a new pattern for a hat. Here it is:

Join in the round and knit as follows:
(K4, P2, K3, P2)* repeat this for 4 rounds.
Round 5: (C4F, P2, K3, P2) until end of round.
Repeat these 5 Rounds until piece measures 5.5 inches from cast on.

My question is what does “C4F” mean? I have never seen these abbreviations before.

Thanks so much for your help!

That means cable over 4 sts held to the front and there should be an explanation somewhere in the notes.

But any way - slip 2 sts to a cable needle, hold them to the front of your work and k 2 from the left needle, then knit the 2 sts off the cable needle.

yup, what she said …
