Forwarding clean up

Whenever I forward an e-mail I try to delete all the addresses of all the 'forwarders' that accompany the e-mail I just received. I other words the only address that appears on the emails that I send out is mine. I am told it's not a good thing to broadcast the email addresses of everyone associated with the messages that I receive and choose to forward.

Occasionally, when I try to delete the forwarding addresses from the message the entire message disappears. It's almost as if there was a hidden 'switch' somewhere in forwarding addresses I am trying delete that erases most of the rest of the message. I can recover what disappeared by starting over but it's annoying.

I am wondering if there is some way to 'Reveal Codes' like in a word processing program that shows all the hidden commands?
