How to make serial.read work in the serial monitor?

Alright, so I just learned from this post Advanced Standalone Serial Monitor that every character that is written into terminal is transmitted to serial. To verify that, I wrote the following short code:

#include <Arduino.h>

void setup() {
  // initiate Serial
  Serial.begin(115200); 
  // wait for serial to come online
  while(!Serial); 
  Serial.println("Serial is ready to accept input");
}

void loop() {
  // put your main code here, to run repeatedly:
}

void serialEvent(){
  while(Serial.available()){
    Serial.print("Serial received > ");
    Serial.println((char)Serial.read());
  }
}

And it behaves as expect. Now I’m going to go research how to transmit only when pressing enter of something like that. I would like to send a character array instead of single characters.
