Implement keyboard navigation for TabStrips

[juancnuno]

When a TabStrip is focused you should be able to navigate between the individual tabs with the keyboard

[juancnuno]

Here is a little Swing demonstration of the keyboard navigation JTabbedPanes have out of the box

import javax.swing.*;
import java.awt.*;

final class Test {
    private Test() {
    }

    public static void main(String[] args) {
        var tabbedPane = new JTabbedPane();
        tabbedPane.setPreferredSize(new Dimension(400, 200));

        tabbedPane.addTab("Tab 1", new JLabel("Tab 1"));
        tabbedPane.addTab("Tab 2", new JLabel("Tab 2"));

        var frame = new JFrame("Test");
        frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);

        var contentPane = frame.getContentPane();

        contentPane.add(new JButton("North"), BorderLayout.NORTH);
        contentPane.add(tabbedPane, BorderLayout.CENTER);
        contentPane.add(new JButton("South"), BorderLayout.SOUTH);

        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

Thank you Juan. I tried keyboard navigation in the UI Sandbox internal action and I can't get the JBTabsImpl to switch tabs with either arrow keys, nor with the tab keys:
