Next tool is the Undo tool. So let's say you're editing an image and you mess up, right. So you screw up right here and I brought the temperature down all the way down, or you just make some kind of mistake. Let's say you bring the vibrance down, and now your image is gone, all your edits are gone. Well, it really, really awesome, easy way to go back is you're going to do a Ctrl or Command C. So you press Ctrl or Command C, you press it twice, because I did the mistake twice, and it brings it back to that original one. And if you make a bunch of mistakes, you can go back as many times as you want to go back to that.
If you only press it once, let's say you did that whoops. All you do is Command or Control Z and it brings you back to your normal image.
