A limit filter shrinks the collection to a smaller size, either by N entities from the front of list, or by a slice within.

    sort=-modified;limit=10

gets the 10 most recently modified entities.

   sort=-modified;limit=10,10

gets the next 10 most recently modified entities (starting at the 11th, slices are zero-indexed).

There's no extension method for limit filters as that wouldn't make much sense.
