This might make sense as an “ejector seat” button for a topic where you don’t want to scroll to the bottom and set a read position, just to get to the Suggested Topics.
I suspect this would need to be a server call, after pressing the hotkey, grab the list of suggested off the server (because they may or may not be in the viewport of the topic yet) and go to the first one?
I think it is a reasonable thing to want, and since it is a hotkey it won’t impact typical users. Can you assign the work @zogstrip?
