create keyboard shortcut event listener in javascript

To create a keyboard shortcut event listener in JavaScript, we can add an event listener to the document object and check if the key combination for the shortcut has been pressed.

Here's an example of how to create a listener for the Ctrl+S key combination:

index.tsx
document.addEventListener('keydown', function(event) {
   if(event.ctrlKey && event.key === 's'){
      // your code here
      event.preventDefault(); // prevent the default save action
   }
});

In this example, we first check if the Ctrl key is being held down (event.ctrlKey) and if the S key has been pressed (event.key === 's'). If both conditions are true, we can run our code to trigger the desired action. In this case, we prevent the default save action by calling event.preventDefault().

You can modify this example to create different keyboard shortcuts by changing the key combination and the code that will be executed when the shortcut is triggered.
