You can try this for your self,

1. Open Cookie clicker
2. turn on mouse keys with the option "CTRL and Shift increase and decrease speed"
3. place your mouse over the Cookie
4. Press CTRL or shift (If one doesn't work its the other)
5. about half a second press and hold 5 and + (Plus) on the number pad. keep on trying until you see what I'm talking about

Basically just an auto clicker

no it isn't
