CloseReview for Copy Plain Text by Art Carnage
Rated 4 out of 5 stars
While the Extended Copy Menu can do the same thing (except it won't trim leading and trailing spaces), the reason to use this is that it works with AutoCopy. I do massive amounts of copying text into form fields, and the AutoCopy/CopyPlainText combo is a lifesaver.
