Anyone know if there is a way to disable the Undo warning popup when selecting all text and then entering additional text. I do this operation all the time in Chatter when replying to an SMS message from a cellphone (due to text count limitations) and it's just a nuisance to have to acknowledge the popup everytime. I leave the Quote option enabled in Chatter because if I'm replying to an actual email address I do want the original message quoted.
