make all layers visible
I can't believe there is no answer to this question, that I can find on this forum, in Photoshop Help or anywhere on the web. I accidentally turned off all my Layers, and now I want to turn them all on again. How do I do that? I found a few posts that said to click and drag across all the visibility icons, but that doesn't work. This is supposed to work in the Layers panel? Nothing happens when I try and click and drag there.
