5. Save the file (with type = All files (*), and extension .ahk, for example: SubSurf.ahk)

5.1. ADVANCED: Feel free to change the code, the delay time for each mouse movement, amount of pixels the mouse will go up/down/left/right, etc. But have in mind that this may make it worse. After my tests, I found this is the best combination.

6. Double-click the file you've saved.

7. Open the game, and press the arrows from the keyboard to move the character.

8. To close the hotkey script you're running, after stopping playing, look at your system tray (near the clock) for an icon wich has an "H", right-click it and press "Exit".
PS: To it work properly, you have to put the cursor near the center of the screen.
