Angular 2+ elegant way to intercept Command+S

Question

Trying to implement a shortcut key combination for Command+S to save a form.

I\'ve read this - https://angular.io/guide/user-input, but it does not say anything about me

Answer 1

1. The methods preventDefault() and stopPropagation() and so on did not work for me (using current Chrome), so i had to go multiple keys: ctrl+shift+s
2. When defining the event handler in my component, it only worked for this subsite and only if some form inputs were in focus, so i had to add the listener at another place.
3. I compressed the multiple functions, since i do not care about which environment the hotkey gets called, i want to save my object.

ngOnInit() {   
  document.body.addEventListener("keydown", event => {
    let charCode = String.fromCharCode(event.which).toLowerCase();
    switch (((navigator.platform.match('Mac') && event.metaKey) || event.ctrlKey) && event.shiftKey && charCode === 's') {
      case true: {
        this.saveArticle(); //whatever your usecase is
        break;
      }
    }
  });
}
