Adds a "b" keyboard shortcut that instantly goes back to the previous page outside text fields.

Code to copy

// Press "b" to go back to the previous page quickly
document.addEventListener('keydown', (e) => {
  const tag = (e.target.tagName || '').toLowerCase();
  if (tag === 'input' || tag === 'textarea' || e.target.isContentEditable) { return; }
  if (e.key === 'b' && !e.ctrlKey && !e.metaKey && !e.altKey) {
    history.back();
  }
});

1. Copy the code with the button above.
2. Install JustZix (2 minutes) and open the extension on the target page.
3. Add a new rule matching that page.
4. Paste the code into the rule's JavaScript panel and save — it runs on every page visit.
