Because directional focus navigation limits the user to moving up, down, left, and right, you may end up with scenarios where parts of the UI are inaccessible (see attached image).

We should provide a way to explicitly indicate how directional navigation will work in some scenarios:

<Canvas>

<Button x:Name="LeftBtn" Content="Left" .../>

<Button x:Name="RightBtn" Content="Right" .../>

<Button x:Name="TopBtn" Content="Top" .../>

<Button x:Name="BottomBtn" Content="Bottom" .../>

<Button Content="Home"

noesis:Element.XYFocusLeft="{Binding ElementName=LeftBtn}"

noesis:Element.XYFocusRight="{Binding ElementName=RightBtn}"

noesis:Element.XYFocusUp="{Binding ElementName=TopBtn}"

noesis:Element.XYFocusDown="{Binding ElementName=BottomBtn}" />

</Canvas>
