Thank you Bob. Thank you Mike.. Here it is my code to move a button
using the arrow keys.

local tSTARTCONTROL

on StartControl
   put "true" into tSTARTCONTROL
   ControlKeys
end StartControl

on StopControl
   put "false" into tSTARTCONTROL
end StopControl

on ControlKeys
   if keysDown() is "65361" then
      MoveLeft
   end if

   if keysDown() is "65362" then
      MoveUp
   end if

   if keysDown() is "65363" then
      MoveRight
   end if

   if keysDown() is "65364" then
      MoveDown
   end if

   if tSTARTCONTROL is true then
      send ControlKeys to me in 0.2 sec
   end if
end ControlKeys

on MoveLeft
   set the left of button "square" to (the left of button "square" - 1 )
end MoveLeft

on MoveRight
   set the left of button "square" to (the left of button "square" + 1 )
end MoveRight

on MoveUp
   set the top of button "square" to (the top of button "square" - 1 )
end MoveUp

on MoveDown
   set the top of button "square" to (the top of button "square" + 1 )
end MoveDown

It works !!

All the best. Paolo
