From Fluent tests, April 2019:
The viewer is not currently keyboard accessible.
Keyboard arrows can only be used as a way of navigating the item when the item has been clicked on. The visually impaired user in particular who defaulted to using the keyboard arrows was confused when this did not work due to the item needing to be clicked on first. Also, the thumbnails or the actual item cannot be selected. As a results, a keyboard-only user cannot navigate to different screenshots and cannot pan around the image with unless they select the image with the mouse.
Consider the keyboard accessibility of the viewer and make it keyboard accessible (e.g. by clearly showing where the focus is and by making the thumbnails and item accessible by tabbing)
As a keyboard user (for accessibility or efficiency reason)
