How do I do a "reply to all" when replying to an e-mail?

How do I NOT include original letters when replying to an email?

• Yahoo automatically includes a copy of the original letter when sending a reply. Can I cancel this feature?

• Answer:

  I don't think so, but what you can do is when you go to reply... ... once you open the reply letter move the cursor to the bottom of the text.. then hold the right button down on your mouse while moving the cursor up the page to highlight the old original letter then back space to delete the Original text. Or can open the reply letter, then do a right click on the middle of letter page, and click on select all , and then hit your back space on keyboard and it will erase the text also, then start typing your letter. Good luck !!
