As it turns out, Mikey, you picked one of the few keys that would actually
do something about changing the focus, etc. when the key is struck. Look at
"tabKey" as the equivalent of "keyUp", meaning that it takes place *after*
the key has been struck, so it actually tabs out of the field (or at least
clears the selectedChunk) before you trap it. What you want to use is
"rawKeyDown" instead:

on rawKeyDown pKey
  if pKey is 65289 then  -- key code for Tab
    get the selectedChunk
    answer it
  end if
  pass rawKeyDown
end rawKeyDown
