Usage

import * as Blockly from 'blockly';
import {NavigationController} from '@blockly/keyboard-navigation';
// Inject Blockly.
const workspace = Blockly.inject('blocklyDiv', {
  toolbox: toolboxCategories,
});
// Initialize plugin.

navigationController.init();
navigationController.addWorkspace(workspace);
// Turns on keyboard navigation.

API

This plugin exports the following classes:

• NavigationController: Class in charge of registering all keyboard shortcuts.
• Navigation: This holds all the functions necessary to navigate around Blockly using the keyboard.
• FlyoutCursor: Cursor in charge of navigating the flyout.
• LineCursor: Alternative cursor that tries to navigate blocks like lines of code.

You should only need to use these if you plan on changing the default functionality.
