I am taking selenium web driver course on test automation university. On chapter 6, the instructor is using mac and is able to send the pi symbol using the following:

public void enterPi(){
        enterText(Keys.chord(Keys.ALT, "p") + "=3.14");
    }

but on windows, I have to hold the alt button and press on 227 on the numpad.

I have tried both chrome and edge drivers but still not working.

This is the fuction I am using:

  public void enterText(String text){

        driver.findElement(formInput).sendKeys(text);
    }

and I tried 3 options as following with actual result I got:

option 1:

enterText(Keys.chord(Keys.ALT, "227") +"=3.14");

got the following:

option 2:

enterText(Keys.chord(Keys.ALT, Keys.NUMPAD2, Keys.NUMPAD2, Keys.NUMPAD7) +"=3.14");

got the following:

option 3: doesn’t use the enterText function

new Actions(driver).keyDown(Keys.ALT).sendKeys("227").perform();
