  Hi Ezerkar,

  Thank you for your interest in OpenSesame!

  No, there's no way to do that through the GUI, but you can set the duration to '0' and add a simple inline_script after the sketchpad:

  # Import and create mouse and keyboard objects
  from openexp.keyboard import keyboard
  from openexp.mouse import mouse
  my_keyboard = keyboard(self.experiment, timeout=5)
  my_mouse = mouse(self.experiment, timeout=5)
  
  # Wait until a key has been pressed or button has been clicked
  start_time = self.time()
  while True:
      resp, time = my_keyboard.get_key()
      if resp != None:
          resp = my_keyboard.to_chr(resp)
          break       
      resp, pos, time = my_mouse.get_click()
      if resp != None:
          break
          
  # Store the response
  self.experiment.set("response", resp) 
  self.experiment.set("response_time", time-start_time)

  Very helpful answer. Thanks too.

  One more detail:
  If I only want certain keypresses, lets say F, G,H, and J, plus any mouse clicks, where do i insert this?

  like that?
  resp, time = my_keyboard.get_key(f;g;h;j)

  Hi,

  The general procedure is explain here and here

  If you want to use both, mouse and keyboard responses, you should sample responses in a loop, e.g. like so:

  
  kb = keyboard(keylist=['j', 'f','g', 'h'], timeout=20)
  # have a low timeout, so that the experiment will not freeze in anticipation for a keyboard response)
  ms = mouse(timeout = 20)
  
  t0 = clock.time()
  while clock.time()-t0 < 5000: # have 5 seconds as response time limit to avoid infinite loops and such
      key, time = kb.get_key()
      if key != None:
          break
      button, position, timestamp = my_mouse.get_click()
      if button is not None:
          break
  

  I hope this helps.
