Deleting or editing bug report

There does not seem to be a way to delete a bug report that I created or even edit it so that I can change the figures.
I see in the the shortcuts that 'd' should delete a topic and 'e' should edit it but this does not seem to work.
Can someone help me?

You mean in GitHub?

No I mean here.

Just delete the thread and recreate it

I would love to, I just don't know how. That's exactly the problem.
