+ * the direction of the encoder everywhere. So encoderDirection is
+ * added to allow the encoder to go the other way.
+ *
+ * This behavior is limited to scrolling Menus and SD card listings,
+ * and is disabled in other contexts.

  * Functions for editing single values
  *
+ * The "menu_edit_type" macro generates the functions needed to edit a numerical value.
+ *
+ * For example, menu_edit_type(int, int3, itostr3, 1) expands into these functions:
+ *
+ *   bool _menu_edit_int3();
+ *   void menu_edit_int3(); // edit int (interactively)
+ *   void menu_edit_callback_int3(); // edit int (interactively) with callback on completion

+ *   static void menu_action_setting_edit_callback_int3(const char* pstr, int* ptr, int minValue, int maxValue, menuFunc_t callback); // edit int with callback
+ *
+ * You can then use one of the menu macros to present the edit interface:
+ *   MENU_ITEM_EDIT(int3, MSG_SPEED, &feedrate_multiplier, 10, 999)
+ *
+ * This expands into a more primitive menu item:
+ *   MENU_ITEM(setting_edit_int3, MSG_SPEED, PSTR(MSG_SPEED), &feedrate_multiplier, 10, 999)
+ *
+ *
+ * Also: MENU_MULTIPLIER_ITEM_EDIT, MENU_ITEM_EDIT_CALLBACK, and MENU_MULTIPLIER_ITEM_EDIT_CALLBACK
