I’ve been going through my pub contributions page correcting the map locations for some time now. I have 85 pages and it can be a real chore scrolling through to the middle pages every time I resume my task.
I discovered today that the page number of the contribution page is at the end of the address bar and the wanted page can be jumped to by editing this page number in the address.

Many of you probably already know this, but I would have saved a lot of time if I had known.
