I think I've read it before. But for something like this, I've got time to read it again...

Oh, yes. Forgot to add the year in the title. Done.

Thanks! Macroexpanded:

Out of curiosity, do you have a script which does this, or do you do it manually?

I do it manually using HN Search but use a browser extension with keyboard shortcuts that make it faster. More here: https://news.ycombinator.com/item?id=28441182.
