This first video is the difference between yarn over and reverse yarn over. In some of my patterns, I do differentiate between the two! If you are a standard Western European/North American knitter, may I please recommend you make the regular yarn over your habit? The regular yarn over will have the same stitch facing as the rest of your stitches, so you won't have to think about it later.
This second video shows the difference between Western and Eastern stitch facings. Neither is right or wrong, but depending on how you knit, you can end up with twisted or plaited stitches when you don't mean to!
This third video shows the four different ways to insert the right needle into the next stitch. You probably already know knitwise and purlwise. If you know how to work a left-leaning decrease (SSK), then you also know knit through the back of the loop. But do you know purl up through the back of the loop?
I hope these videos will help make the more peculiar instructions in my patterns more intuitive.
