ArrowKey Handler in LiveCode 8?

[Scott Rossi]

If you want to recreate the behavior of previous versions of LC, you can
do something like this:

on arrowKey theKey
   if the selObj is empty then pass arrowKey
   put loc of the selObj into theLoc
   put 1 into D
   if the shiftkey is down then multiply D by 10
   switch theKey
       case "left"
           subtract D from item 1 of theLoc
           break
       case "right"
           add D to item 1 of theLoc
           break
       case "up"
           subtract D from item 2 of theLoc
           break
       case "down"
           add D to item 2 of theLoc
   end switch
   set loc of the selObj to theLoc
end arrowKey
