seleniumm java 中点击发送 tab 键

package com.example.demo;

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 org.openqa.selenium.interactions.Actions;

import java.awt.*;
import java.awt.event.KeyEvent;

public class Test {
    public static void main(String[] args) throws Exception {
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.google.com/");
        driver.manage().window();
        WebElement input = driver.findElement(By.xpath("/html/body/div[1]/div[3]/form/div[1]/div[1]/div[1]/div/div[2]/input"));

        // 输入框输入内容
        input.sendKeys("seleniumm");

        // 清除内容
        Robot robot = new Robot();
        robot.keyPress(KeyEvent.VK_TAB);
        robot.keyPress(KeyEvent.VK_ENTER);


        // F5按键刷新页面
        Thread.sleep(2000);
        robot.keyPress(KeyEvent.VK_F5);
        driver.quit();
    }
}

搜了很多不生效，只有使用 Robot 会生效
