title: How to clear text field before sending keys selenium c#
body: <p>I'm writing a simple selenium test which sends an incorrect string of letters then submits and returns and error. I want to then send a string of letter but this time with the correct string so it is accepted.</p>
  
  <p>The issue i'm facing in my test is as the first set of string is already in the text field, so when i go to the submit the second one it adds it on to the first string that has already been submitted.</p>
  
  <p>So what i essentially need to do is send the first string of letters then need to clear the text field then send the second string of letters. </p>
