the short-cut key can just open the app, hopefully it could close the app when click the 'short-cut' key again

It seems like you are describing the default behavior of an application when using a shortcut key. When you click the shortcut key again, the window will close but the application will not completely exit. Based on your description and the previous issue, it is likely that you have inadvertently opened two instances of the same application. Please try running only one instance of the application to resolve the issue.
