Hey there! Sorry if this has been discussed somewhere - I promise I searched before posting. 
We have quite the backlog of issues in a couple repos and I’ve taken it upon myself to start at the beginning, going through all the issues and testing » commenting/closing and found myself wishing there was some kind of “explore mode” allowing me to open an issue, test, comment, maybe close, then hit an arrow key or keyboard shortcut to get to the next issue. Currently I have to open issues in new tabs or navigate back to the issue list when I’m done testing/closing an issue. I looked but couldn’t find any feature allowing easy exploration of issues. Did I miss it? If not, is that a reasonable feature request? I think what I said made sense but please let me know if I can clarify.
