OK, I'll save you time. Here's the script. It monitors the mouse every second. If it's moved, the F1 key is pressed. You can change that, of course. You can compile it with the tool provided with Autohotkey and run the exe before MaLa so that it stays resident.
#Persistent 
#NoTrayIcon
SetTimer, monitorcursor, 1000 
monitorcursor:
IfWinActive MaLa ahk_class TfrmMain 
   if !chk_mousepos() 
   send, {F1} 
return    
chk_mousepos(input=false) 
{ 
   static mousex, mousey 
   if !mousex OR !mousey 
      MouseGetPos, mousex, mousey 
   MouseGetPos, mousex2, mousey2 
   if (mousex = mousex2) AND (mousey = mousey2) 
      return true 
   else 
   { 
      mousex := mousex2 
      mousey := mousey2 
      return false 
   }    
}
