#### 3.5.4.4 Modifying the Headers: ~h, ~t, ~c, ~b, ~s ¶

To add new addresses to the list of message recipients, use ‘`~t`’ command, e.g.:

    ~t name1@domain.net name2

To add addresses to `Cc` or `Bcc`, use ‘`~c`’ or ‘`~b`’ escapes respectively.

To change the `Subject` header, use ‘`~s`’ escape, e.g.:

    ~s "Re: your message"

Finally, to edit all headers, type ‘`~h`’ escape. This will present you with the values of `To`, `Cc`, `Bcc`, and `Subject` headers allowing to edit them with normal text editing commands.
