Message navigation with keyboard

I use my keyboard as much as possible. And I love discord because it provides me with great hotkey support. The navigation between different servers or channels is great. But when I get into a certain channel I can't easily scroll through my messages.

My suggestion is to make the arrow keys scroll through messages. The desktop Slack application has this feature implemented, and I think it's great. They even have special shortcuts for when the message is highlighted (r for react, p for pin, e for edit...). I think that this would be a great addition to discord.
