PS CC keyboard shortcut Opt+Cmd+Z not working (osx mavericks)
Since I deleted the Adobe and Photoshop preferences from my library folder, I'm facing a weird issue:
Any keyboard shortcut that involves the Option/Alt key on my keyboard is simply not recognized by Photoshop. I have confirmed that my physical key is not broken and works in all other applications, but when I use it in Photoshop, nothing happens. When I go to the keyboard shortcuts menu and try to modify 'Step Backward' (because I really want this key do be like the default), I cannot put in the Option key. I can use different combinations for the command, just not this one key.
Does anybody have an idea what is going on and how to fix this? I have deleted the preference files once more and rebooted, but no change. I haven't installed any other software or drivers in a long time, so I doubt it's because of anything interfering with Photoshop. I also checked for double assigned shortcuts in the system, but as I said, PS simply won't recognize that the Alt key is pressed.
