title: Sending keystrokes to a program
body: <p>In window form, I made a button and I'm trying to make it send <kbd>F1</kbd> to a specific window (Such as FireFox, My Computer, etc...)</p>
  
  <p>My questions are : </p>
  
  <ul>
  <li>How do I do it by the window's name? (such as "Mozilla Firefox")</li>
  <li>How do I do it by the process's name? (such as firefox.exe)</li>
  </ul>
