Creating a shortcut in javascript with 5 lines of code!
To create a shortcut, we must first listen to the pressing of the keyboard keys on the document
Then specify the keys we want to simplify with an if
Finally, we have to eliminate the normal behavior of that shirt with preventDefault

// Listen to keydown event on the document
document.addEventListener("keydown", (e) => {
  if (e.key.toLowerCase() === "s" && e.ctrlKey) {
    // disable the default behavior of the ctrl + s
    e.preventDefault();
    // your code here
    alert("S key pressed with ctrl");
  }
});
