 The Node.js Web Crypto API extends various aspects of the Web Crypto API.
 These extensions are consistently identified by prepending names with the
-`node.` prefix. For instance, the `node.keyObject` key format can be
+`node.` prefix. For instance, the `'node.keyObject'` key format can be
 used with the `subtle.exportKey()` and `subtle.importKey()` methods to
 convert between a WebCrypto {CryptoKey} object and a Node.js {KeyObject}.
