@jeremycherfas On the Mac, I leave “smart quotes” enabled. When I need to use "straight quotes", I hold down Ctrl while typing the character, so a "straight double quote" is Ctrl-Shift-', and a 'straight single quote' is Ctrl-'. When the smart quotes get it wrong and I need to type curly quotes directly, an open double quote “ is Option-[, a close double quote ” is Option-Shift-[, an open single quote ‘ is Option-] and a close single quote ’ is Option-Shift-]. It’s more straightforward than it sounds.
