You are mixing up control structures. The "case" statement has to be 
part of a "switch" structure. It should be like this:

if what is in "HJKLI:;" then
   switch what -- need this
     case "J"
       -- stuff
       break
     case "K"
        -- stuff
        break
   end switch -- need this too
end if

Actually, you don't even need the "if" part; the switch structure itself 
will test for the contents of "what". So you could just do it this way:

on controlkeydown what
    switch what
     case "J"
       -- stuff
       break
      case "K"
        -- stuff
        break
      default -- this should probably be in there too
        pass controlkeydown
     end switch
end controlkeydown
