-The `LinkTitle` method returns the `linkTitle` field as defined in front matter, falling back to the value returned by the [`Title`] method.
-
-[`Title`]: /methods/page/title
-
-{{< code-toggle file=content/articles/healthy-desserts.md fm=true >}}
-title = 'Seventeen delightful recipes for healthy desserts'
-linkTitle = 'Dessert recipes'
-{{< /code-toggle >}}
-
-```go-html-template
-{{ .LinkTitle }} → Dessert recipes
-```
-
-As demonstrated above, defining a link title in front matter is advantageous when the page title is long. Use it when generating anchor elements in your templates:
-
-```go-html-template
-<a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
-```
