I've got your back on this question about scrolling down pages in QuickBooks Online (QBO).
The Page Down or Page Up keys are unresponsive on the Bank Reconciliation page. What you can use is the mouse wheel to scroll up or down on that page.
You can refer to this article on keyboard combinations you can use in QBO: Keyboard shortcuts for QuickBooks Online. Instead of moving the mouse point all over the screen, you can use the shortcuts listed so you can navigate the system faster.
