You can't see everything too good here because of the video compression, but there's an area behind the text that lights up when you hover it. Click and drag on that with the LMB to move stuff around. You can use the scroll wheel too, which I also do in the video, although it kinda looks like I'm dragging because of the mouse sensitivity. It's not easy being accurate while recording.
I'm thinking of removing the arrows, as they're really not needed (maybe if your scrollwheel is busted). :shrug:
