A Specifies the cursor after which to fetch items

B Limits items to the first N

C Sorts items alphabetically

after tells the server to return items after the given cursor.

If you want the next 5 items after a cursor, which arguments do you use?

A <code>limit: 5</code>

B <code>first: 5</code> and <code>after: cursor</code>
