Welcome! You'll like it here.
I find that after many years of knitting that I automatically give an extra pull to the yarn as I switch back and forth. You can see the stitch tug up to the needle. I'm sure at first I had to do it consciously, but it became second nature after a while.
This is an example of how it pays to actually watch what happens when you knit rather than making the stitches and then wondering what you did.
I hope this helps.
