Getting help

mail has two screens of online help that show you the available commands.

To get help when you are typing a message, go to a new line and type ∼?
(tilde-question mark). This is called a ``mail compose escape;'' you use these
escapes to give a command to the mail program while you are typing a message. The help screen shown lists all
the mail compose escapes.

To get help when you are reading your mail, type ? at the mail prompt. The help screen you see shows the commands available when you are reading your mail.
