The salute is used in the presence of other scouts as a form of greeting. It also connotes a sign of respect. The three fingers of the salute each have a separate meaning. These are Honor God and the King, Help Others, and Obey the Scout Law.
This detailed meaning of the three fingers is universal for scouting. There are some variation. Cubs scouts salute with two fingers. And in the United States, the salute is reserved for being in the presence of the American flag. You normally do not salute other scouts here in the USA.
