title: Processing keyPressed()
body: <p>basically I have to use Processing for a project (not out of choice) and have come across a problem regarding the pressing of multiple keys at once. In the <code>keyPressed()</code>function, I have multiple conditionals, each mapping a key to an action. This is all well and good, but supposing I want to press multiple keys at once?</p>
  
  <p>Any suggestions?</p>
  
  <p>Thanks.</p>
