    <Button x:Name="fourth">Fourth</Button>
</StackPanel>
public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();

        // Override the default flow for next/previous items in 
        // UI Automation to differ from the sequence of items 
        // declared in markup
        FlowBetween(first, second);
        FlowBetween(second, third);
        FlowBetween(third, fourth);
    }

    public void FlowBetween(UIElement fromElement, UIElement toElement)
    {
        // Set up the flow as bi-directional so that moving next/previous is
        // consistent.
        var flowsToList = AutomationProperties.GetFlowsTo(fromElement);
        var flowsFromList = AutomationProperties.GetFlowsFrom(toElement);

        flowsToList.Add(toElement);
        flowsFromList.Add(fromElement);
    }
}

Remarks

Get the list, then call the Add method to add a new element.

[!Important] > When modifying the flow, be careful not to create a situation where the user gets stuck in a navigation loop that they can't escape if they are only using a keyboard.
