Re: the control key acts as a pause button

Yes, this is mentioned somewhere in the voiceover documentation, or  
in the keystroke list, or something like that. and, I agree, it is a  
very handy little thing to know about.
And, I also agree that I believe it is unique to voiceover.  Artic  
had a keystroke to use to speed up speech, but not a key to stop and  
then resume where it left off, only temporarily silence speech while  
the computer was still outputing text.
