scroll through buttons with arrow keys

I want to scroll through different buttons using the up and down keys like this. sorry i don’t really know a better way to explain it

Short of getting a GUI package from the Asset store that does this for you, I would look into using GUI.FocusControl and make sure you have styles set up that hightlight things differently when focused (GUIStyle.focused) Detect those keys in Update and set the focus accordingly.
