//contract if you go to far with //expand. And //sel to clear the current selection to retry it. But nice video man! Glad to see a good tutorial on this!
This was before I realized they had been given //contract. IMO, it is a bit easier just to start over if you overshoot your //expand EDIT: I am adding a video showing you how to use those three commands. Thanks bajj! (See guys, suggestions WORK! )
