If you need to handle a key combination which is not listed above, you can do so by handling the PreviewSyntaxEditorKeyDown event.

Example 1: Handling the Ctrl+S keyboard combination

C#

    private void SyntaxEditor_PreviewSyntaxEditorKeyDown(object sender, PreviewSyntaxEditorKeyEventArgs e)
    {
        if (e.Key == Key.S && KeyboardModifiers.IsControlDown)
        {
            e.OriginalArgs.Handled = true;
        }
    }
