A better solution is to "pass" the message if you don't use it. I
would write your handler like this:

on commandKeyDown theKey
  switch theKey
  case "a"
    if the selectedField is not empty then
      select text of the selectedField
    end if
    break
  default
    pass commandKeyDown
  end switch
end commandKeyDown

This makes it so that ANY command key shortcut that doesn't get caught
in your switch statement, will get passed up the message hierarchy for
your app or the Rev engine to process. It is generally a good idea to
"pass" all system messages if you don't use them.
