I just downloaded Premiere Pro CC onto my Mac running Mavericks. None of the typical keyboard shortcuts were working when I started to edit a video so I looked at the keyboard shortcuts preferences. All of the keyboard shortcut versions that came preloaded even the default are all empty. I'm not willing to go through and add the shortcuts for every key. Can I download what should be the default list of shortcuts and reinstall it? Clearly something didn't install correctly. HELP!
