List/Library Next 20 items at top of page

At the bottom of a list or library you can click next 30 items or whatever you item limit is set to. AS well there is an add new item at the bottom.

I have found on google how to add the "add new Item" button to the top of the list by using a content editor and java.

I need to find the same type of solution for the "next 30 items" button.

Does anyone know the java code i would need to add to a content editor above the list?

Thanks so much!
