=== NOTES ===

To modify your mouse speed just modify your code; instead of 5 put any multiple of 5.

If it is not working, try erasing the brazilian words from the code.

Now you can control your mouse using your NumPad: Crt+alt+NumPad to move:

Crt+alt+8  -> Move up

Crt+alt+2  -> Move down

Crt+alt+6  -> Move right

Crt+alt+4  -> Move left

Crt+alt+9  -> Move up right

Crt+alt+7  -> Move up left

Crt+alt+3  -> Move down right

Crt+alt+1  -> Move down left

Crt+alt+Enter  -> left click

Crt+alt+0  -> right click
