title: Sending keystrokes to an unfocused process pywinauto
body: <p>I'm trying to send keystrokes of regular keyboard input from 'a-z' which may or may not include the directional arrow keys to a running game process, however i'm confused at the pywinauto documentation:</p>
  
  <p>I've already connected the existing process via pid by:</p>
  
  <pre><code>from pywinauto.application import Application
  from pywinauto.keyboard import SendKeys    
  app = Application().connect(process=1234)
  #app.SendKeys('a')? Doesn't seem to work
  </code></pre>
  
  <p>I've read some other answers on this but it's not very clear as to what the next step is on the documentation, there aren't any real examples.</p>
  
  <p>I've also read from some other answers that SendKeys auto focuses the windows, which isn't want I want, if possible would it be possible to send keystrokes to the process silently?</p>
