How to simulate the Back Button Click

I am using the kantu plug-in for FireFox on windows 7. Is there a goback command?

What I am doing at the moment is, I created a label and use the open command to go to my starter page. I would like to simulate a back button press, is this possible?

Thank you

You can do this with storeEval and the Javascript command window.history.back()

      "Command": "storeEval",
      "Target": "window.history.back()",
      "Value": ""
