Submit input when "Enter" button is pressed from the keyboard

Create an element that can be clicked or use one that already exists and at the bottom of the editor for that element enter the HTML ID attribute of “enter”. You can make this element invisible through styling. Get the free plugin called “Toolbox”. Then on a “Page is loaded” workflow use the action “Run Javascript” and put the following code:

$(window).keydown(function(e) {
     if (event.keyCode == 13) {
          if($('#enter').length){
               $('#enter').click();
          }
     }
})

Now you can use a When Element is Clicked workflow on the element you gave the “enter” id attribute.

Note: If you haven’t done so before then you may need to go to your apps settings in general and check the box to expose html element id attributes
