Navigate list items with j/k keys
The j and k keys move a Vim-style selection across list items and scroll them into view.
Code to copy
var items = Array.prototype.slice.call(
document.querySelectorAll('article, li, .item, [role="listitem"]')
).filter(function (el) { return el.offsetHeight > 20; });
var idx = -1;
document.addEventListener('keydown', function (e) {
if (e.target.matches('input, textarea, select, [contenteditable]')) { return; }
if (e.key !== 'j' && e.key !== 'k') { return; }
if (!items.length) { return; }
if (idx >= 0) { items[idx].style.outline = ''; }
idx = e.key === 'j' ? Math.min(idx + 1, items.length - 1)
: Math.max(idx - 1, 0);
items[idx].style.outline = '3px solid #006870';
items[idx].scrollIntoView({ behavior: 'smooth', block: 'center' });
