how can I stop (or break) script with mouse move

Question

I'm using some script for my Indesign document. But i want to stop script when mouse cursor not move. When script run mouse moving in text (its normal). When the text it finish doesn't move any more, but script still working for loop finish. can i stop it when cursor not move. Here is sample of my script

  Loop 100
{
Send ^{Numpad3}
Send ^{Down}
Send ^{Numpad2}
Send ^{Down}
}

Answer 1

This stops the loop if the mouse is moved

MouseGetPos, x1,y1 
Loop 100
{

  MouseGetPos, X2, Y2

  if (X1 <> x2) or (y1 <> y2)
    break


  Send ^{Numpad3}
  Send ^{Down}
  Send ^{Numpad2}
  Send ^{Down}
}
