The index finger or forefinger is the second finger of a human hand, located between the thumb and the middle finger. It is usually the most dexterous finger of a hand and is usually used to point to things (a direction, an object etc.), thus it is also called the pointer finger.
Gestures
As mentioned above, the forefinger can be used for pointing. However, this gesture is considered rude in some countries (Brunei, for instance), and other gestures are used instead.
A lone index finger often is used to represent the number 1, or when held up, it can be an admonitory gesture.

There are six index finger symbols in Unicode.
