+### Menu templates
+
+If a [display config section](Config_Reference.md#display) is enabled,
+then it is possible to customize the menu with
+[menu](Config_Reference.md#menu) config sections.
+
+The following read-only attributes are available in menu templates:
+* `menu.width` - element width (number of display columns)
+* `menu.ns` - element namespace
+* `menu.event` - name of the event that triggered the script
+* `menu.input` - input value, only available in input script context
+
+The following actions are available in menu templates:
+* `menu.back(force, update)`: will execute menu back command, optional
+  boolean parameters `<force>` and `<update>`.
+  * When `<force>` is set True then it will also stop editing. Default
+    value is False.
+  * When `<update>` is set False then parent container items are not
+    updated. Default value is True.
+* `menu.exit(force)` - will execute menu exit command, optional
+  boolean parameter `<force>` default value False.
+  * When `<force>` is set True then it will also stop editing. Default
+    value is False.
