This is not a modal Window, hence why the delete is activated by the delete button in the keyword hud and not the delete key. I’m not sure I’d want to change this?
Okay… I see this problem is ancient. I don’t know, what a modal window is, I only know what I want to do and I know that it doesn’t do what I expect it to do. Nice to see that this has been noted. Hope it will be dealt with eventually.
