This action is straightforward: from one or multiple source Worksheets,you can navigate to a TargetSheet (Worksheet, Dashboard, or Story). The following screenshot shows the configuration window, when you add aGo to Sheet... action:
In this configuration window, you can specify the following:
The Name of the action
The Source Sheets
The trigger (Hover, Select, or Menu)
The Target Sheet (Worksheet, Dashboard, or Story)

The second new action allows you to create new ways to interact with your Worksheets.
