[Script] script to focus window inside of hit area

I used to have a tampermonkey script that focused the window inside of the hit area so that you don't have to click inside the window to use the keyboard to work on hits and submit hits with enter on each new hit, but it stopped working a long time ago. Is there currently a script like this that works or another way to do this?

 

Code:

// ==UserScript==
// @name         Focus
// @include     https://www.mturkcontent.com/*
// ==/UserScript==

window.focus();

 

Thank you!
