The Problem
The arrow keys need to scroll an email when it is open, rather than navigating to the next message. This is extremely important to a keyboard workflow, and it is very disruptive when I have no option to read a message besides moving to the mouse.
Proposed Solution
When a message is open, arrow keys should scroll.
Alternative Solutions
Make scrolling a configurable keybind.
Context
Gmail works this way. I already use Gmail hotkeys because I’m trying to replace my usage of Gmail.
