JS routine to give Keyboard Maestro custom HTML prompts a timeout function. The timeout is automatically paused as soon as a key in pressed in a text input field so that it won't time out while someone's typing.

Keyboard Maestro HTML Prompt Timeout

<script>

var timeout;

function KMInit() {

var dialogTimeout = 10000

timeout = setTimeout(function(){ window.KeyboardMaestro.Submit('Timeout'); }, dialogTimeout);

  $('input[type=text]').keypress(function() {
console.log('Clearing timeout');
          clearTimeout(timeout);
  });

};

</script>
