You are correct that it should be enough just to say Ubuntu, but it is
not uncommon for people to ask questions about Ubuntu and eventually
discover they are using Mate or something and neglected to mention it.
Ctrl-Alt does not do anything on my 12.04 Unity.  I guess you have
looked in System Settings > Keyboard > Shortcuts > Windows > Close
Window, and in
System Settings > Keyboard > Shortcuts > Custom Shortcuts

Otherwise I don't know.
