+### Usage with cross-tab-copy-paste plugin
+
+This plugin adds context menu items for copying & pasting. It also adds feedback to copying & pasting as toasts that are shown to the user upon successful copy or cut. It is compatible with the `@blockly/plugin-cross-tab-copy-paste` by following these steps:
+
+```js
+import * as Blockly from 'blockly';
+import {KeyboardNavigation} from '@blockly/keyboard-navigation';
+import {CrossTabCopyPaste} from '@blockly/plugin-cross-tab-copy-paste';
+
+// Inject Blockly.
+const workspace = Blockly.inject('blocklyDiv', {
+  toolbox: toolboxCategories,
+});
+
+// Initialize cross-tab-copy-paste
+// Must be done before keyboard-navigation
+const crossTabOptions = {
+  // Don't use the context menu options from the ctcp plugin,
+  // because the keyboard-navigation plugin provides its own.
+  contextMenu: false,
+  shortcut: true,
+};
+const plugin = new CrossTabCopyPaste();
+plugin.init(crossTabOptions, () => {
+  console.log('Use this error callback to handle TypeError while pasting');
+});
+
+// Initialize keyboard-navigation.
+// You must pass the `allowCrossWorkspacePaste` option in order for paste
+// to appear correctly enabled/disabled in the context menu.
+const keyboardNav = new KeyboardNavigation(workspace, {
+  allowCrossWorkspacePaste: true,
+});
+```
