I'm not completely sure I understand what the problem is, but this
should work:

  on controlKey theKey
    if theKey is 26 then -- control-Z was typed
      sendSerial numToChar(26) -- or however you're sending characters
    else pass controlKey
  end controlKey

The controlKey message is sent whether or not a field is currently
open for editing.
