I'm sure this has come up before, but a cursory search of meta didn't turn up anything relevant. On occasion I have downvoted an answer, but then the author edited it and I felt that it didn't deserve the downvote any longer. However on a few occasions, I felt that though a downvote was no longer warranted, I still didn't want to upvote the answer. However, when I click on the appropriate arrows on the left, after having downvoted an answer, the only thing I seem to be able to do is convert the downvote to an upvote as opposed to converting it to "no vote." Is there a way to do this, or is this something on SE's radar?
I did a quick experiment on 5 previous questions that I previously voted on, but have since been edited (surprisingly easy to find, actually). Simply clicking on the arrow of my vote successfully removed my vote. So if I had downvoted, I clicked on the downvote arrow and it went away. Upvote - I clicked on the upvote and it went away.
I then put them back, by the way.
Does that not work for you?
