Inbox - Keyboard Navigation?

[GC28]

Hi all,

Possiblly a strange one, I've used the up and down arrows on my keyboard to navigate through emails in the inbox.

I've found this temperamental this year.

 

For instance: Once continue is hit and processing finishes, hitting the up or down arrows navigate through the sidebar menu.

 

Hitting space to move to the next message works but not the up and down arrows to navigate through them following this, I am wondering if it’s just a behaviour I have or possibly by design?

I've found clicking on a message with the mouse enables the up/down arrows for navigating through the inbox. Dunno if it's intentional or not.
