​Feature Request: Allow arrow keys to scroll through photos

It would be great if readers could use the left/right arrow keys on their keyboard to scroll through photo gallery collections, instead of having to use their mouse and click on the < > arrows. I'd even like to see this enabled on article assets that have multiple photos displayed at the top.

This is a feature that is enabled on so many websites that I personally get annoyed when I come across one, like our own, where it isn't.

What do y'all think?

EDIT: Here is a good example, the photos are about halfway down the page.

The arrow keys work to move through the photos both as they are embeded in the article and also if you use the gallery or thumbnail view option to make them larger.
