Enable the use of the left/right arrow keys in embedded prototypes in order to give users possibility to scroll artboards. I know it works if all artboards are not wired, but it should work also if these are wired. Like in prototypes or preview. It is not clear why is it excluded from embed mode.

Some prototypes have multiple clickable hotspots so users have to search for them and learn their way through. Giving them possibility to use common arrow keys is a way to get sure they will be able to see all artboards and find their way back if they get stuck.

I have made myself a tool to view prototypes with a device frame around it www.xdskin.com, to share designs easily with my clients. It's based on embedded prototypes and it would be great if my clients could, alternatively to clicking hotspots, switch to prev/next artboard by using their keyboard arrow keys.
