Quotes problem in Mavericks (or TextEdit) TextEdit in Mavericks changes the standard double quotes "Hello" to using curly, non-ascii quotation marks “Hello”.  It does this even when you edit plain text documents.  Is there a way to prevent this new behavior in Mavericks?
This is not just TextEdit, it's Mavericks.

Under System Preferences > Keyboard, you can change the quotation marks.

Go to the 'Text' sub-menu.  On the right-hand side of the box, uncheck the "Use smart quotes and dashes" checkbox.
