N/A

According to the following code in MetalFileChooserUI.java, Metal doesn't use mnemonics for these buttons:

private void doApproveButtonMnemonicChanged(PropertyChangeEvent e) {
    // Note: Metal does not use mnemonics for approve and cancel
}

Either this should be changed, or the docs should be brought in line to mention that the use of mnemonics is L&F dependent.
