I accidentally upvoted a comment and a box appeared. (Since I don't keep a ledger of my votes.) How can I erase the errant vote?

I was afraid to hit the flag icon. Is there a way to tell when I have already voted?

To answer both your questions - an upvoted comment has a highlighted up arrowhead, and clicking on it again gives you a prompt asking you if you want to undo an upvote. You can only undo it once though.

    This is no longer possible once one reloads the page - it only works on the same page load as the one where one upvoted the comment. Mar 4, 2023 at 0:09
