• If there is more than one maximum/minimum, you can use d and e to move
between them.
• If there is only one graph, pressing 2 (MAX) / 3 (MIN) directly displays the
maximum/minimum (selection of the graph is not required).
• Note that the above operation can be performed on rectangular coordinate (Y=)
and inequality graphs only.
