I have entered the Apple Script exactly as dfay indicated in the first post. Dictation works perfectly. When I say "Press Return Key", a short message box (Press Return Key) appears above the dictation microphone and the cursor advances one line. I still must manually hit the Enter key to stop dictation. And yes, I have enabled dictation commands in System Preferences-Accessibiliry-Dictation Commands-Enable Advanced Commands. What am I missing?
