Sketchflow Navigation

I am new to Blend & Sketchflow. I hope someone can help me.

I have been doing a sketchflow project and have set up several buttons that navigate to specific screens (nice and easy).

Now the catch...

I have made a generic menu at the top, and have put a button on it, and what I want to achieve with it is that if someone clicks on that button, instead of navigating to a specific screen, it simply navigates to the previous screen that was viewed in sketchflow.

Does anyone know if this is possible? And if so, how I would achieve this?

Solution

Use the "back" behavior. There are 2 easy ways to apply this behavior to your button:

Right click the button in the artboard, select "Navigate To" -> "Back" or
Open the assets panel, SketchFlow->Behaviors->NavigateBackAction, drag this behavior onto your button.

The xaml should look similar to this:
