Yes, knitting back backwards. A handy thing to know and I use it especially to do stranded color work on the return rows so I can keep the right side facing me. I can't do it as fast as regular knitting or even regular purling but it has its uses. Some people get very adept at it (sounds like Sheri is one).
I do it Continental as well, but don't really throw the yarn, but do it pretty much the way I do when I purl, i.e. do it with my left middle finger. It is also easy to do holding the yarn in your right hand.
When you finish knitting your row don't turn, just insert the left needle into the first stitch behind the right hand needle left to right, so kind of purl wise. Then wrap the yarn. (If you do it Continental it goes over the top of the bottom needle [so between the needles] and around to the back. English it is the same, but took me a while to figure out :lol: ) Then lift the loop on the right hand needle over the end of the left hand needle and let the the loop off the right hand needle. Or you can use your left hand a little more and think of that last step as pulling the stitch loop up like you do right handed.
Bobbles are another thing this works good for.
