What do you do if you unintentionally trash a thread?

[Xyzse]

How could you tell if you did?
How could you undo it?

I am not sure if I did that, but I've never used that feature before, nor was I planning to.
So I don't know if I did or not.

Yes, I am sure the topic was not that important, but I would never know.

1. Up at the top of the page, there is a row of tabs. One of them is "my account."

Click that tab, and inside there are more tabs! One of them is Trash thread. If you click on that, it will show you what you trashed. And there is an option to change that.

2. Oh-Hohoho

Cool, I have not trashed a thread after all.
I just saw my browser pop up an option asking me if I am supposed to trash a thread.
Glad there is nothing there.

4. Some threads are better in the trash.

I know Peggy already gave you the answer.
