Navigation between children

Hi wisemen
I would like to add some simple navigation between one parent's children, like this http://img211.imageshack.us/img211/969/modxlt3.jpg

I found in this forum that this can be done with docLink, but I cannot get it, maybe there's some new snippet I can use, cause the thread I found was 3 years old.

P.S. I'm using Evo 1.0.3

That should be possible with Ditto.
Have a look to the parameters &display, &paginate, &paginateAlwaysShowLinks,
&tplPaginateNext and &tplPaginatePrevious:

By the way: For security reasons, you should upgrade to Evo 1.0.5.

You may also try with PrevJumpNext snippet.
