I'm following along with a tutorial and I must have hit some button and now it's seriously hindering my ability to follow along. When i try to select and edge the target edge turns green and the edges next to it turn red, when i modify the target edge the others react as well. I know its some sort of group modify tool or something, but I have no idea how to turn it off and clearly it wasn't intended in the tutorial. https://gyazo.com/2b1e257a29ff05a9eadff95312bc0c3eEdit:
After googling 50 different ways I found an old post on some other website, apparently I had hit the "b" key and turned on soft select.
