Filter by user
If you want to read before, or after, a filtered post, you can look up the actual post number
In the above example it is @zephyr1 9/9 post in the topic. But by clicking the link button, it displays the actual post is #128.
This allows you to go to post #128 and then scroll up or down.
You can also hit refresh page on your web browser, but sometimes that will move you to a random post further up the topic.
