I've been using Photoshop for years (currently CS6, Version 13.0 x64) and have never really had any problems. A couple of weeks ago, I was normally using Photoshop and I realized none of my keyboard commands were working. When I look under File, Edit, Image etc., the keyboard commands show that they are not set. These commands work fine in other Adobe programs.
Undo ⌘ ≠
Step Forward ⇧ ⌘ ≠
Step Backward ⌥ ⌘ ≠
I've tried resetting the settings file through deletion of the file itself as well as deleting the file upon startup.
A screenshot is attached.
