I just realized now that when the lock is active on a layer/object it doesn't do anything. What do I mean? I mean, when I put the lock on a layer, I can move keyframes on the timeline to another point in time. I can change the properties of a particular keyframe, I can delete the layer/object. I can double click on the timeline blue bar to add a keyframe. The only thing it does it lock the object on the stage so that you can't select it. So, in the one instance of wanting to select one object behind another object, locking works. But this is the way locking works in, say, Illustrator, but not in, say, After Effects, where you can't even delete the layer, or in Photoshop, where image adjustments and filters get grayed out so they can't be applied. Shouldn't the lock lock everything to do with that layer/object?
