Previous post number .. if you look at the address in the tool bar, you will see that it ends with the 'thread number', 2770536. If you go back to the 'previous page', the address will then end with the number of the 'first post on that page' .. you can change that number to any post you wish, to go straight to it.
I often knock 500 off the number to take me back a week, to see what was being highlighted then, to see how they have progressed.
