new possible feature for pagination

[publicocean0]

i m improving my jquery plugin for pagination adding also pagination by rid.
In general case i have a high number of pages and preload all rid page could be huge. So it is necessary to use a lazy method.
if i go forward in the navigation i can always to find the new page rid because

• or is in the plugin cache
• i can execute (page-1)*pageSize skip pageSize for finding the new rid and page (page -1 is known if i go forward).
  If i go backward instead and i dont know the rid (not previously read)
  i might execute (page)*pageSize skipback pageSize (i know page rid)

so a new possible feature is to introduce SKIPBACK keyword :)
example
select from A where @Rid< #5:1000 skipback 10;
