title: How to press enter key if the input is hidden?
body: <p>I have some porblem with the iMacros coding. I would like to write a macro to comment posts in social media. I do not have any problem with the easy part, go to page, tag the textarea and write a content. This is ok. However there is no post, or comment, or send or any button to enter the text I want to comment. I tried DS but th version I have can't handle that. I just can't believe that this is so difficult to comment something if there is no button for it. I copy the html part:<a href="http://i.stack.imgur.com/fhIPF.png" rel="nofollow">this is the html part of the story</a></p>
  
  <p>So I hope you can help me to find out how to generate a hidden input keypress ENTER for me :) THX!</p>
