Besides simply indicating "up," this emoji is effective at guiding the flow of a conversation to a specific point. It plays a role in focusing people's attention when sharing important notices or links online.

In digital communication, this finger is like a powerful indicator light. It's also useful for denoting the first item on a list or wittily emphasizing your own opinion, like "See, I was right, wasn't I?" Try using it when you agree with a friend's opinion to say, "That's it!"
