Question about a cable pattern in the SnB Nation book

So I decided to do the Belt de Jour pattern for the Interweave Press One Skein secret pal project. (Anyone else know about this program? It’s fun!)

Anyhow, here’s the part that loses me:
Row 3: Sl1 pwise, p1, cable patt row 3, p2.

And the cable pattern row 3 is:
C4b, c4f

Ok, I’ve done cables once before and the directions tell me when to slip the stitches, whether to put them in back or front, etc. Basically, a true idiot’s step-by-step guide. These directions from the SnB Nation book assume things, I think, for the sake of brevity.

So my question: when I reach this part of the pattern, do I slip 4 stitches onto the cable needle, drop it in back, knit the next 4 stitches from the left needle, throw the cable needle to the front then knit those? What does it mean?!

Thanks in advance for all the help, guys!

C4B is generally "Slip two stitches to your cable needle, hold in back of work. Knit next two stitches, then knit stitches from cable needle."
C4F would be the same, except you hold the needle in front.

You’re doing two cable crossings here, one after the other. The number (4 in this case) is the total number of stitches in the cable rather than the number you slip onto your cable needle.

Tab, thanks! That helps a lot! I shall begin today!
