Your naivete could be corrected by reading the manpage on curses.

Performing a keypad() will enable the keypad on most terminals, and when
the user presses an arrow key, the return value will be KEY_DOWN, KEY_UP,
etc.  You can then take the proper action based on the key that the
user actually pressed.
