Shortcut key bindings for cross platform look & feel(metal l&f)

Question

I was reading about the cross-platform look & feel ie the metal L&f that looks the same across all platforms. I wanted to know what will be the shortcut keys for this l&f. I'm facing an issue where in MAC OS, if I have to copy/paste I have to use window shortcuts(ctrl + v/c) for copy/paste actions.I'm unable to use mac shortcuts (cmd+v/c). I'm wondering if it could be due to the l&f. Please help.Thanks in advance.

Yes, the look and feel can do this. One thing you can do, which I hope somebody has a better answer, is to set the input map for the components you want to behave differently. Here's a way to use the platform default input map for a text field.

public static void startGui(){
    try{
        LookAndFeel aqua = UIManager.getLookAndFeel(); //aqua
        UIDefaults def = UIManager.getDefaults();
        Object b = def.get("TextField.focusInputMap");
        UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
        UIDefaults def2 = UIManager.getDefaults();
        def2.put("TextField.focusInputMap", b);
    }catch(Exception e){
        e.printStackTrace();
    }

    JFrame frame = new JFrame("title");

    JTextField field = new  JTextField();
    frame.add(field);
    frame.setSize(640, 480);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);
}
public static void main(String[] args) throws Exception {
    EventQueue.invokeLater( ()->startGui() );
}

If you run that, then cmd+v should paste, but if you commend out the line def2.put(...) then ctrl+v will paste.
