If you see the image I posted in #3 you will see I dont have that icon.It's done by hovering over what I circled in red.
you have 28 posts and your account is 6 days old. i'm guessing you're not allowed to use that system yet, as an abuse prevention measure. believe it or not, some people don't have anything better to do with their time than make new accounts for the purpose of circumventing the limit on number of reactions a day in order to mass downvote people.
