Knitting Stitch Bible Twisted Rib....HELP!

The twisted symbol part isn’t explained. I know that you have to knit thru the back loop but what is the stitch immediately to the left and to the right?

I checked the glossary and couldn’t find anything.

So what I see is:

Row 1: P,P,?,KBL,?,P,P,?,KBL, etc.

Any code breakers out there?

Thanks!

What page is it on?

If it’s the one on page 84, it’s p2, the 3-st cable on page 253, p2

:muah:

(Oh dear, it IS in the glossary. I’m such a dolt. Maybe I should stick to crocheting or think a little harder before I post my “D’oh!” questions.)
