How to press ENTER inside an edit box in Selenium?

Selenium gives Enum Key macros to perform the enter action.

Example

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import java.util.List;
public class PressEnter {
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url = " https://www.tutorialspoint.com/index.htm";
      driver.get(url);
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
      // Keys.ENTER passed through sendKeys() method
      driver.findElement(By.className("gsc-input")).sendKeys("Keys.ENTER");
      driver.close();
   }
}
