Do UK keyboards have separate keys for ``curly quotes''? My US keyboard has only one key that has the (as you put it) feet and inches marks and another key that has the backtick. I've never seen any separate keys for real quotation marks.

Or do you just mean in typesetting? (My sordid experience with TeX has made me start using `` and '', personally. (That's two backticks and two ``feet marks'', which TeX translates into real quotation marks.)
