java - Mac Keyboard Shortcuts with Nimbus LAF

Question

Is there a way to use Nimbus LAF (Look And Feel) on OS X while still being able to use the Meta key for cut/copy/paste and select-all operations?

I currently have the following code in my Swing app's main method, which changes up the LAF based on the operating system (default for OS X, Nimbus for all others):

if (!System.getProperty("os.name", "").startsWith("Mac OS X")) {
    try {
        for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
            if ("Nimbus".equals(info.getName())) {
                javax.swing.UIManager.setLookAndFeel(info.getClassName());
                break;
            }
        }
    } catch (ClassNotFoundException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (InstantiationException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (IllegalAccessException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (javax.swing.UnsupportedLookAndFeelException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    }
}

I do this as a workaround because Nimbus overrides the keyboard shortcuts for cut/copy/paste and select-all on OS X (Meta key versus Ctrl key). I would prefer to use Nimbus all the time, if only the keyboard shortcuts weren't overridden.

Using the getMenuShortcutKeyMask() method works with NimbusLookAndFeel to enable the ? key, as shown in this example. See also this related answer.

In the particular case of a JTextField, you can use the mask in a key binding that evokes the original action.

int MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();
JTextField jtf = new JTextField("Test");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_A, MASK), "select-all");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_C, MASK), "copy");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_X, MASK), "cut");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_V, MASK), "paste");
