Yes that answered all my questions! There’s a faster simpler one for non-textured styles here: UE4 - Easy Gamepad and Keyboard navigation in UMG menus - YouTube
I found for myself also that text input widgets don’t need any blueprint checking to set focused style (they have a focused style already, along with the usual normal/hover/pressed styles), but buttons do need some extra logic to get them to change style on Focus/Blur since they don’t have that.
