Get past paywall - for sites that disable scroll - use this to scroll up/down with a/z keys respectively

enableScroll.js

function KeyPress(e) {
  const { keyCode } = window.event ? event : e;

  // If "a" is pressed, scroll up
  if (keyCode == 65) {
    window.scrollBy(0, -100) 
  }

  // If "z" is pressed, scroll down
  if (keyCode == 90) {
    window.scrollBy(0, 100) 
  }
}

document.onkeydown = KeyPress;
