Has anyone figured out a way to create a layer mask in E3? I'm trying to do some editing of some photos, and really want a layer mask. I know you could do it in Elements 2 by holding down the 'alt' key while opening a 'ripple' filter, but apparently that doesn't work in E3... I'm dying to have a layer mask and I really don't want to have to load E2 just to do it...
