How do Christian believers gesture when they shout Amen?

The general gesture is to clasp hands and cross them. The gesture of drawing a cross on the chest is usually made by Catholics. Christianity does not have this gesture and requires a prayer from the heart as a sign of devotion. Catholics and Eastern Orthodox require the right hand to be spread out with the five fingers together and the middle finger pointing to the forehead, chest, left shoulder and right shoulder. The heart recites "In the name of the Father, and of the Son, and of the Holy Spirit. Amen." When you point to the forehead, say "In the name of the Father", when you point to the forehead, say "In the name of the Son", and when you point to the right shoulder, say "In the name of the Holy Spirit" with both hands.

Prayer gestures: The Bible mentions various ways of praying. Matthew 6:5 "When you pray, do not be like the hypocrites, who love to pray standing in synagogues and at crossroads, that they may be seen by men. Matthew 6:6 "And when thou prayest, enter into thy inner chamber, and when thou hast shut thy door, pray to thy Father which is in secret: and thy Father which seeth in secret shall reward thee." ?

Matthew 17:21 " But as for this kind of demon, unless he prays and fasts, he will not come out." From the above verses, we can see that there is no time, place, or manner for prayer.
