Used to, when you held your mouse over an emoji with which someone reacted to you, a little tooltip would show up telling you what that emoji is and who issued it. Now, you have to click them to find out the who; it still doesn’t show WHAT the emoji is and some of these new emjois people are using… I have no CLUE what they are!
But occasionally I really AM curious about what one might be, so you can do this:
When you copy the emoji, you are copying that missing description. So just paste it into your text editor, and voila! There is the text description. Or just paste it in the search bar of your open-already browser (you don’t have to actually enter and perform the search so you won’t lose your page).
(Obviously this is for those of us not on a mobile device, I have no idea what to do on there.)
