+The primary application for this function is the definition of the `namedSlices` parameter in the options map passed to the `.Related` method on the `Page` object.
+
+See [related content](/content-management/related).
+
+```go-html-template
+{{ $kv := keyVals "foo" "a" "b" "c" }}
+```
+
+The resulting data structure is:
+
+```json
+{
+  "Key": "foo",
+  "Values": [
+    "a",
+    "b",
+    "c"
+  ]
+}
+```
+
+To extract the key and values:
+
+```go-html-template
+
+{{ $kv.Key }} → foo
+{{ $kv.Values }} → [a b c]
+```
