Locking artwork in Illustrator

…Hi there.…Welcome back to Creative Quick Tips.…My name is Justin Seeley.…And in this video, I'm going to be talking about a shortcut that I use all the time…inside of Adobe Illustrator and it wasn't until recently…that I realized, not many people know about it.…And it's something that I really take for granted…because it's something that makes my life so much easier.…First of all, let's go through a scenario.…So let's say that we're working on this slide.…This is a slide for a recent presentation that I was doing.…And, as you can see, it's got a lot of different objects on the slide.…And what I want to do is, I want to be able to…quickly and easily edit all of these small details in the middle.…

And so, what I might do is try to click and…drag a selection around those objects to make a change to them.…Unfortunately, when I try to click and drag,…I wind up moving my background layer, and…that really frustrates me, because then I have to reset it, and then I have to…go in here and I have to manually click on stuff, and it just makes it…
