index pointing up

It's an image of a finger pointing upwards. It's often used to emphasize important content or draw attention.

It's frequently used online to say "Look at this" or "Check the above." It's a particularly popular emoji on social media and in messages.

This emoji is one of the representative gesture expressions that has existed since the early emoticon era of the 1990s. It has been universally understood to mean "attention" or "emphasis" regardless of culture.

Academically, it has been studied as one of the most basic forms of human non-verbal communication. It's particularly effective as a gesture to focus an audience's attention in educational settings or presentations.
