<P> Snapping (or clicking) one's fingers is the act of creating a snapping or clicking sound with one's fingers . Primarily this is done by building tension between the thumb and another (middle, index, or ring) finger and then moving the other finger forcefully downward so it hits the palm of the same hand at a high speed . </P> <P> In Ancient Greece snapping of fingers was used by musicians and dancers as a way to keep the rhythm and it was known with the words "ἀποληκέω" (apolekeo), "ἀποκρότημα" (apokrotema) (from the verb "ἀποκροτέω" - apokroteo, "to snap the fingers") and "ἐπίπταισμα" (epiptaisma). Finger snapping is still common in modern Greece . </P>
