+
+In this menu definition, the second entry does not contain an `identifier`, so the `Identifier` method returns its `name` property instead:
+
+{{< code-toggle file=hugo >}}
+[[menu.main]]
+identifier = 'about'
+name = 'About'
+pageRef = '/about'
+weight = 10
+
+[[menu.main]]
+name = 'Contact'
+pageRef = '/contact'
+weight = 20
+{{< /code-toggle >}}
+
+This example uses the `KeyName` method when querying the translation table on a multilingual site, falling back the `name` property if a matching key in the translation table does not exist:
+
+```go-html-template
+<ul>
+  {{ range .Site.Menus.main }}
+    <li><a href="{{ .URL }}">{{ or (T (.KeyName | lower)) .Name }}</a></li>
+  {{ end }}
+</ul>
+```
+
+In the example above, we need to pass the value returned by `.KeyName` through the [`lower`] function because the keys in the translation table are lowercase.
