Same, and I could also see myself compulsively using Ctrl+A Ctrl+C to get it on my clipboard just in case. I already do this in webforms (like on HN) because of so many years of losing my text.

I like this idea but I think it would be great if the text went into a recycle bin instead of fully gone. At least for me that would still accomplish the desired result, but I wouldn't live in fear of losing some important point because I took too long proofreading or something.
