on arrowKey theKey
   switch theKey
      case "Up"
      case "Down"
      case "Left"
      case "Right"
   end switch
   pass arrowKey
end arrowKey

Pretty simple. You can also use the keysDown() function which will return the same codes as rawKeyDown, so write a couple simple scripts to see which codes are for which arrows. They may not be the same on all platforms tho' so test with Windows, Mac and Linux to be sure. 

In the card script put:
on escapeKey
    answer "Keysnatcher is off!" as sheet
    exit to top
end escapeKey

In a button on the card put:
on mouseUp
       repeat
           put keysdown() into theKeysDown
        if theKeysDown is not empty then
            answer theKeysDown as sheet
        end if
        wait one second with messages
       end repeat
    pass mouseUp
end mouseUp
