AutoClick does mouse clicks for you when you're unable to click, or when clicking is an opeation that takes a lot of effort.
When the mouse pointer STOPS moving, AutoClick counts down a fixed interval and orchestrates a mouse click. This may cause you to click more than normally, but there's a lot of space to direct the click to when you don't need the click (e.g. the application caption bar), and if you think about it, in most cases you move to somewhere to click there. Switching modes enables double-clicks, drag operations, and rolling the scrolling wheel!
