 * Three navigation types are provided:
 *
 * NAV_THREE_KEY:
 *  left, right -> change option
 *  up, down -> don't matter (change row)
 *  start -> move to next row
 *  left+right+start -> move to prev row
 *  (next screen via "exit" entry)
 * This is the minimal navigation, for using menus with only three buttons.
 *
 * NAV_FIVE_KEY:
 *  left, right -> change option
 *  up, down -> change row
 *  start -> next screen
 * This is a much more convenient navigation, requiring five keys.
 *
 * NAV_THREE_KEY_MENU:
 *  left, right -> change row
 *  up, down -> change row
 *  start -> next screen
 * This is a specialized navigation for ScreenOptionsMenu.  It must be enabled to
 * allow screens that use rows to select other screens to work with only three
 * buttons.  (It's also used when in five-key mode.)
