Field Keyboard Functions

[FMoyer at aol.com]

Oops.  I actually did have the "Switch"  and "Default" and "End Switch" lines 
in there -- but forgot to type them into my email letter. To be more 
complete, what I have is:

on controlkeydown what
  if what is in "JKL:;i" and the selectedchunk is not empty then
    put the selectedchunk into sc
    put the selectedloc into sl
    put the shiftkey into s
    put the optionkey into o
    put last word of sc into fieldNumber
    put fld fieldnumber into holder
    switch what
    case "j"
      if s is down then
        if o is down then
          --stuff
        else
          --stuff
        end if
      else
        if o is down then
          --stuff
        else
          --stuff
        end if
      end if
      break
    case "k"
      --stuff
        .
        .
        .
    default
      pass controlkeydown
    end switch
    break
  else
    pass controlkeydown
  end if
end controlkeydown
