title: How to raise an event when Enter is pressed into an InputText in PySimpleGUI
body: <p>i'm new with Python &amp; PySimpleGUI and i don't know how to force my application to handle the event  key; this is my code:</p>
  <pre><code>    # Text field
      sg.InputText(
          key=key,
          default_text='',
          enable_events=True,
      ),
  
  
      ...
  
  
      window = self.graphic_interface.window
  
      while self.is_running:
          self.event, self.values = window.read(timeout=0)
  
      ...
  
  
      if event in INSERT_SN_KEYS:
          key = event
  
          if values[key]is not None:
              # Accept only numbers
              if values[key][-1] not in '0123456789':
                  window[key].update(values[key][:-1])
  </code></pre>
  <p>My code can handle any key pressed by user except ; i haven't found any argument for  InputText similar to &quot;bind_return_key=True&quot; used into Button class.
  How can i do it?
  Thanks</p>
