Editing a message before you send it
To edit a message you are creating,
press <Esc> and select
Edit from the Create menu to start
the editor program configured for your account.
Exit the editor using its normal quit command.
You can edit a message using a text processing program other than the editor built into SCO Shell Mail.
To define a different standard editor, select:
Options
from the Mail menu.

Move the highlight to the Mail Editor line, and change the pathname for the editor program to the one you want to use. Ask your system administrator if you do not know the pathname of the editor program.
