When you ask to complete a find, it may find many cards which fit the description you provide. You select from the Find list which card you want to see first, but it wouldn't be terribly convenient to have to return to the list every time you wanted to see another card on the same topic. Clicking the down-arrow of the Card icon will move you to the next card which fits the description you provided to the find engine. The Up-arrow takes you to the previous match. When you reach the last find, you are asked if you would like to wrap around to the first match. The up-arrow is similarly functional. If you have not yet made a find request, the arrows do nothing.
