How do you "TWIST" a stitch

I recently purchased a kit from Australia. It is a vest and has cables on it which is something new for me. I am a novice knitter but wanted a challenge. I came across this instruction “twist, p1” and have no idea what they mean by twist.

Can anyone help?

Thanks for ending my confusion. Hope

In this case, it simply means to twist the stitch. For example, if you are a combined knitter, ( your purl stitch would already be twisted. Similarly, you can look at Amy’s video for untwisting a stitch( so that you can twist a stitch. Backwards, huh? You could manually twist it, but it’s probably easier to just go through the opposite side of the loop. Any help from anyone more versed that me (which is most of you)?
