how to add a formatting menu bar to Atom-“cut", "copy", "paste".

I study HTML, chose the atom editor.
Please tell me how to add a formatting menu bar to Atom-“cut", "copy", "paste". It is uncomfortable to work without them.

The issue asks how to add cut, copy, and paste controls to Atom’s formatting menu bar, but names no file, test, or entry point. Start by checking the package documentation and Atom toolbar capabilities; done would be clear instructions or documentation explaining whether this is supported.
