 So you don't know how to swivel, not a problem. If target is set to edge loop and you left click on an edge it will swivel that edge around a pivot. Where the pivot is depends on the face, your mouse was hovering over when you left clicked. So if this face is glowing red then the pivot point will be here, but if this face is glowing red then the pivot point will be there. It also works for partial edge loops too, so if you click on an edge that has points that are only connected to three edges it will stop the swivel at those points. And if target is set to single edge it will look like a normal expand movement control, but that is because it's trying to swivel from two points at the same time. For this target to work properly you have to click on an edge that is surrounded by open faces. So if we delete a few faces and then click this edge you will see it swiveling like so. Hope that helps and as always hope you have a fantastic day and I'll see you around.
