need help controling stepper motors

Hi i made a pan tilt with arduino uno and two stepper motors and i used this code to control it :

#include <Stepper.h>

const int stepsPerRevolution = 15;

Stepper Motor1(stepsPerRevolution, 8,9,10,11);
Stepper Motor2(stepsPerRevolution, 4,5,6,7);

void setup() {
Motor1.setSpeed(30);
Motor2.setSpeed(30);
Serial.begin(9600);
}

void loop() {
Serial.println("clockwise");
Motor1.step(stepsPerRevolution);
delay(100);
Motor2.step(stepsPerRevolution);
delay(100);

Serial.println("counterclockwise");
Motor1.step(-stepsPerRevolution);
delay(500);
Motor2.step(-stepsPerRevolution);
delay(500);
}

and now i want to control my motors from the keyboard using for example the directional arrows (left and right arrow control a motor and the up and down the second motor), also im pretty bad at programming so please make it as easy as possible for me to understand also if you can't give me the code please give me the library and the commads i'll figure it somehow . Thank you for the help.

Using what application on the PC? The Serial Monitor does not monitor ALL the keys. Specifically, the arrow keys are ignored.
