PROPERLY Addressing Nano Pins in sketches - much confusion

Not that literally.

#define pin11 11
#define pin12 12

Here's some fancy code defining pin numbers based on the Arduino model in use.

#if defined(ARDUINO_AVR_UNO)
 #define LED_OUT 13
 #define SENSOR_INPUT_PIN 2
 #define START_STOP_PIN 12
 #define SCROLL_PIN 11
 #define MODE_PIN 10
 #define LBO_PIN 3
 LiquidCrystal lcd(8, 9, 4, 5, 6, 7);           // select the pins used on the LCD panel
 #define Timer1_OCR1A 249
#elif defined(ARDUINO_AVR_PRO)
 #define LED_OUT 13
 #define SENSOR_INPUT_PIN 8
 #define START_STOP_PIN 12
 #define SCROLL_PIN 11
 #define MODE_PIN 10
 #define LBO_PIN 9
 LiquidCrystal lcd(7, 6, 5, 4, 3, 2);           // select the pins used on the LCD panel
 #define Timer1_OCR1A 124
#else
  #error Unsupported board selection.
#endif

It works 100%.

The issue I think your are running into is the Reset pin. It is not coded within the Arduino IDE as a digital input pin. I would first have to ask why you need to detect the reset being pressed and how you will execute any program prior to the hardware reset activating? You will need write custom code in order to see that pin press.
