U+1F446 · emoji since 2010
The finger pointing up draws your eye upward, to the message above, a previous point, or this, exactly this.
It seconds an opinion, highlights a reply, and gives a silent agreement with whatever came just before.
In texting, 👆️ does not carry a widely used hidden or slang meaning, so you can usually take it at face value. People send it just as it looks, to add a little visual touch or set the mood of a message. Only a handful of emoji have a separate texting code, and 👆️ is not really one of them.
Its official Unicode name is the Backhand Index Pointing Up emoji. In everyday chat most people just call it the backhand index pointing up emoji or describe what it shows. Copy and paste it from the button at the top of this page.
The 👆️ leads off a short phrase, and the rest of the words are written in cipher, every letter disguised as another emoji. Tap decipher to reveal the whole line.
Or make your own cipher in the translator.
