At times it may be practical to clone an action to make minor modifications to an existing one. Here's how.
In the Actions node on the Workflows tab in the configuration there is a row of icons to the far right for every marker you have made. To clone an action you click on the first icon with the green arrow. The cloned action will be added to the bottom of the list, and you can easily modify it by clicking on the Edit button (the middle one of the three) and change the settings for the action as needed.
