The arrow keys do useful things in the identify modal. Right/left to move to the next/previous observation, alt-right/left to look at different photos in the current observation. However, the up/down arrows don’t do anything. It would be great if they could scroll the list of IDs/comments if that list is longer than the window is tall. That would duplicate the functionality of a scroll wheel, but notebook computers don’t tend to have those.
The other keyboard shortcuts are very useful, I use them all the time. I’d like to also read the ID’s comments without moving my hand over to the trackpad.
