Save the Output Window contents to a file

I can’t believe I didn’t know this. I was looking for a way to save the output window contents to a file. Couldn’t see a button for it on the toolbar, couldn’t find a plugin. Then I found this post.

It contains some great facts that I wasn’t aware of, one of which was that if you click in the output window and press ctrl+s it will save the current window contents to a file.
