Page 120 Communicating Using Your Handheld Computer
Creating e-mail items
You create e-mail items with your handheld computer the same way
you create e-mail with your desktop e-mail application: you identify
the recipient(s) of the e-mail item, define a subject, and create the body
of the e-mail item.
You create original e-mail items and replies in the New Message
screen. All e-mail items must, at the very least, contain information in
the To: and Subj: fields.
