How do I turn on smart quotes?

I have the Localized Options in AutoCorrect set up properly (I think) so that it replaces single and double quotation marks with curly quotes, but as I type the straight quotes keep showing up and there seems to be no way to convert them except to search through and convert them that way – but if I apply AutoCorrect it undoes all the other formatting in the paragraph, so it’s too inefficient for me to use. Isn’t there any way to turn on smart quotes as I type? This wasn’t a problem for me back in 6.1, but they must have made some pretty drastic changes in 6.2…

Help! Please answer this! Smart quotes is a very necessary feature! Please Please Please!
