In the English language specifically, curly quotes are not the " and ' marks found on a standard keyboard. These marks are properly reserved for mathematical notations, non-typeset material, and informal communications such as email. There are two separate double curly quotes (open or left quote and closed or right quote) and separate single curly quote symbols. It can vary by typeface, but typically the opening or left quote mark is an inverted and reversed version of the closed mark. They might be described as looking like tiny 6's and 9's (with the counters closed in)
- On a Mac, use Option+] and Shift+Option+] for the left (open) and right (closed) single curly quotes. For Windows, use ALT 0145 and ALT 0146 for the left and right single curly quotes (hold down the ALT key and type the numbers on the numeric keypad).
- On a Mac, use Option+[ and Shift+Option+[ for the left and right double curly quotes. For Windows, use ALT 0147 and ALT 0148 for the left and right double curly quotes.
