Meaning
A hand seen from the back with the index finger pointing to the right. It directs the reader onward: toward what comes next in the sentence, a link, a call to action, or the next item in a list.
It is a staple of announcements and sales posts: βFree shipping this week only π order before Sunday.β It can also single out a person, as in βAnd the raffle winner is π Minh!β Used too often in a post it looks like spam, and pointing it at a specific person in a heated discussion can feel accusatory.
