@REPOn the page you get back from a 'Search' request at the top of the list of the first 10 stories are the page numbers 1 through to 7. On of the boxes with the number at the top has and up arrow and down arrow in it - on the first page it's the first box, but once you move along a few pages it usually moves to being the middle box number. If you use those up and down arrows you can cycle through to the page number you want, then you click the mouse at it jumps to that page. Also, you can highlight the number in that box with the arrows and type in the number of the page you want to go to, and then hit enter and it goes there. Thus it already does what you want in 2 ways.
Edit to add: I've noticed, and used, these same boxes on every story list I've seen on the site.
The only problem I've encountered with that is when you go over 999 pages it only displays the first 3 digits of the page number so 1000 to 1009 only displays as 100.
Lazeez, can you set that to display 4 digits with the arrows when required, please.
