How to use Sendkeys() without finding element on web page when element is already focused and waiting for input

Try this - WebElement currentElement = driver.switchTo().activeElement();

Refer to this for more details - https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/WebDriver.TargetLocator.html#activeElement--

Alternatively you can use the ROBOT function as a workaround.For example: to send 123456 you may use

Robot robot = new Robot();      robot.keyPress(KeyEvent.VK_1);robot.keyRelease(KeyEvent.VK_1);robot.keyPress(KeyEvent.VK_2);robot.keyRelease(KeyEvent.VK_2);robot.keyPress(KeyEvent.VK_3);robot.keyRelease(KeyEvent.VK_3);robot.keyPress(KeyEvent.VK_4);robot.keyRelease(KeyEvent.VK_4);robot.keyPress(KeyEvent.VK_5);robot.keyRelease(KeyEvent.VK_5);robot.keyPress(KeyEvent.VK_6);robot.keyRelease(KeyEvent.VK_6);robot.keyPress(KeyEvent.VK_ENTER);robot.keyRelease(KeyEvent.VK_ENTER);

I have also used the Sikuli sendkeys feature in the past succesfully.

Use below code for the same :

driver.findElement(By.tagName("body")).sendKeys(Keys.TAB);

I have tried the demo and its fine

public static void main(String[] args) throws InterruptedException {        System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");        WebDriver driver = new ChromeDriver();        driver.get("https://www.google.com");        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);        driver.findElement(By.tagName("body")).sendKeys(Keys.TAB);        Thread.sleep(1000);        driver.findElement(By.tagName("body")).sendKeys(Keys.TAB);        Thread.sleep(1000);        driver.findElement(By.tagName("body")).sendKeys(Keys.TAB);        Thread.sleep(1000);        driver.findElement(By.tagName("body")).sendKeys(Keys.TAB);        Thread.sleep(1000);        driver.findElement(By.tagName("body")).sendKeys(Keys.TAB);        System.out.println("OK");    }
