Do the G5 have a quick tapping function? If it does, how can I obtain it

[AC Question]

Some contest I enter require you to tap on the screen as fast you can in order to win. I do not have cheetah fingers like others. Someone told me that a function like that exists. Help me out o life please. A feature or function
