Ubuntu Unity Alt Problems

Ubuntu Unity would give me problems in World of WarCraft when I pressed alt or other key combinations. I hope this helps

1. Go to Ubuntu Software Center
2. Search for and install "gconf-editor"
3. Run gconf-editor either from Dash Home or the command line
4. Click on the Apps folder->metacity->general
5. Click on mouse_button_modifier
6. Type <Super> instead of <Alt>
