[OS X TeX] type regular double-quote in TeXShop?

[Murray Eisenberg]

In TeXShop (), how does one type an ordinary text double-quote mark (looking like this: '') rather than one built up from two single-quotes (which is what TeXShop inserts, along with the pair of left back-quotes, when I strike the double-quote key)?
