After you finish dictating to Hal you can click on the "Stop" icon or you
click "Speech" and then click on "Stop Dictation". You can also click on the
"Microphone" icon to just pause the dictation session and then click on the "Micorphone"
icon again to resume the dictation session. The "Microphone" icon toggles your
computer's microphone on and off.
After you completed dictating your entire document to Hal all you have to do is just save
it by clicking on "File" and then click on "Save" or "Save As".
