 ### Update the shortcuts JSON file
 
-To define localized strings for your custom shortcuts, you must specify tokens in your add-in's shortcuts JSON file. The tokens name strings in the localization resource file, which you'll create in a later step. The following is an example that assigns a keyboard shortcut to a function (defined elsewhere) that displays the add-in's task pane. Note the following about this markup.
+To define an alternative keyboard binding for another locale, you must specify tokens in your add-in's shortcuts JSON file. The tokens name reference strings in the shortcuts JSON file and the localization resource file, which you'll create in a later step. The following is an example that assigns a keyboard shortcut to a function (defined elsewhere) that displays the add-in's task pane. Note the following about this markup.
 
-- The tokens must have the format **${resource.*name-of-resource*}**. The resource name must match the applicable locale string specified in the localization resource file.
-- Default strings *must be defined in the extended overrides file itself*. Default strings are used when the locale of the Microsoft 365 host application doesn't match any of the *ll-cc* properties in the resources file. Defining the default strings directly in the extended overrides file ensures that Microsoft 365 doesn't download the resource file when the locale of the Microsoft 365 application matches the default locale of the add-in (as specified in the manifest).

 ### Create a localization resource file
 
-The localization resource file, which is also JSON-formatted, has a top-level `resources` property that's divided into subproperties by locale. For each locale, a string is assigned to each token that was used in the shortcuts JSON file. The following is an example which has strings for `en-us` and `fr-fr`. In this example, the keyboard shortcut is the same in both locales, but that won't always be the case, especially when you're localizing for locales that have a different alphabet or writing system, and hence a different keyboard.
+While the default shortcuts and strings are defined in the shortcuts JSON file, the localization resource file configures alternative keyboard shortcuts for one additional locale. The localized strings defined in this file are used when the language of the Microsoft 365 host application matches the **ll-cc** property specified in the file.
+
+Similar to the shortcuts file, the localization resource file is also JSON-formatted and includes strings for the alternative locale. A string is assigned to each token that was used in the shortcuts JSON file. The following is an example of alternative strings for `es-es`. Note that keyboard shortcuts may differ from the default when localizing for locales that have a different alphabet or writing system, and hence a different keyboard.
 
 ```json
 {
-    "resources":{ 
-        "en-us": { 
-            "ShowTaskpane_default_shortcut": {
-                "value": "CTRL+SHIFT+A"
-            }, 
-            "ShowTaskpane_action_name": {
-                "value": "Show task pane for add-in"
-            }, 
-        },
-        "fr-fr": { 
-            "ShowTaskpane_default_shortcut": {
-                "value": "CTRL+SHIFT+A"
-            }, 
-            "ShowTaskpane_action_name": {
-                "value": "Afficher le volet de tâche pour add-in"
-              } 
-        }
+    "showTaskpane_action_name": {
