Lets you switch product gallery photos with the left and right arrow keys, no mouse needed.
Code to copy
// Browse the product image gallery with the left and right arrow keys
document.addEventListener('keydown', function (e) {
if (e.target && /^(INPUT|TEXTAREA|SELECT)$/.test(e.target.tagName)) { return; }
if (e.key !== 'ArrowLeft' && e.key !== 'ArrowRight') { return; }
const thumbs = document.querySelectorAll('[class*="thumbnail"] [class*="item"], [class*="slider--item"]');
if (!thumbs.length) { return; }
let idx = -1;
thumbs.forEach(function (t, i) {
if (t.className.indexOf('active') !== -1) { idx = i; }
});
let next = e.key === 'ArrowRight' ? idx + 1 : idx - 1;
if (next < 0) { next = thumbs.length - 1; }
if (next >= thumbs.length) { next = 0; }
thumbs[next].dispatchEvent(new MouseEvent('mouseover', { bubbles: true }));
