I am new to Photoshop and being an artist I need command option Z. It works whenever I click step backward on the edit tab, and then the shortcut will work a couple of times and then randomly stops. I looked at other forums and stuff and people were saying something where they'll just click option command and it changes the language and glitches somehow? But I looked all over keyboard shortcuts and my laptop's settings but see nothing like that. Please help???
