I know that by default they are all named 'op'. This is my problem; I cannot distinguish the buttons by their '#value', because it is always the same. I'm solving this by setting the '#name' to allow me to determine precisely which button was clicked. If I don't set '#name', then *regardless* of which button I press, the 'clicked_button' structure in the $form_state corresponds to the last button of the same '#value' added to the form. Part of the awkwardness here is that HTML doesn't allow you to display some text in a button while having a different value.
