Contain the sign editor in a command

I am fairly sure that 99% of the times I've opened the editor it has been unintended and has lead to a few deaths in game. I am so tired of the editor turning signs into a mild annoyance or at worst into a cause of ingame death.

If you make it so you have to shift+click that works as well,  that would also be better. I just dont want to open a sign when I'm drawing my bow or opening a chest.

Yes, they can be waxed, but that also means you can't edit storage or other more fluid signs, which also is sub-optimal.
