Accessibility issue: Add focus when navigating using keyboard

[jjcraze9]

Summary

Focus is a border that appears on screen around the highlighted interactable to show where a user is on the screen while navigating using keyboard.

Basic example

Motivation

Users with mobility issues often use keyboards to navigate rather than a mouse, without focus it is impossible to tell what button you are "clicking" when you hit enter
