Reply To: Singe left-pointing angle quotation mark

There are two places to look:
First: Check the “Dictionary” section of Preferences dialog box. What are the single- and double-quote options set to?
Second: select the text and check what language it’s set to in the character formatting section of the Control panel (or Character or Properties panel). If it’s set to, say, “French,” then you’ll get different quotes than if it’s set to English.
