When I compose an email in yahoo, how do I set my Mac to detect the contact with a few letters?

Every Dell I've ever used automatically produced a list of potential contacts when I would begin entering a contacts name in the "to" line from my yahoo account. I now have a Mac, and I have to click "insert contacts" and then search for the person's name each time I write an email. I'm sure there is a simple way to fix this, anyone know how?

This should have nothing to do with what computer you have, as the e-mail program is the same for all computers. Just try writing in the first 2 letters of the name, then the contacts will all come up. Then click on the one you want.
Reply:Try it this way In Yahoo:


1. After you click on Compose or Forward to open the Compose Page, click on TO and your address book will open on top of the page you are in.


2. Check the boxes (To, Cc or Bcc) next to those you wish to Send to.


3. Go to the top of the list and click on "Insert Checked Contacts."


The address book will close and the names you selected will be in the fields you selected.
