Auto Clicker by Shocker can simulate single or double clicks by your left, middle, or right mouse buttons at intervals you select, including pauses, freezing the cursor, and stopping automatically after a predetermined number of clicks. The first auto clicker appeared not long after the first mouse, and since then they've evolved alongside mice. Some auto clickers have stayed simple, though. Like primitive but successful organisms that have found their niche, the most basic form of auto clicker lives on, emulating mouse clicks on demand. Auto Clicker by Shocker is as good a specimen as any. You can also set a hotkey to stop the clicks on demand.
Three by three describes Auto Clicker's interface. With three File Menu entries, three buttons, and fairly close to 3 inches square on the screen, Auto Clicker is simplicity encoded. The three main buttons start and stop the clicks and open an Online Support page that includes a contact form. The only command under File is Exit, but the Options menu contains three (naturally!) choices: Click, Group, and Settings. We opened the Clicking Options and set our Mouse and Click choices on drop-down lists. We could also check a box labeled Freeze the pointer to keep the cursor from moving during clicking. Under Group/Interval we could set the optional Autostop feature to stop clicking after intervals of a certain number of clicks.
