I have articles sorted under year => month folders (udatefoldersy) like above and would like to use Previous and Next to navigate to the next or previous article. This obviously doesnt work with CurrentPage.Next and CurrentPage.Previous and couldnt figure out an elegant way to do with Up/Down and Next/Previous - if you consider year-> month and date sorting especially.

Any advise how one can achieve this, within article view context do Prev and Next by date order?
