Snippet Explanation

This code snippet adds a JavaScript event listener to the update button on the post edit admin view. When the user presses the Command + S keyboard shortcut on a laptop, the code will trigger the update button click event. This allows the user to quickly save their post to the WordPress database with the shortcut, rather than manually clicking the button.
