The MOVE command is synonymous with the FILE command. Moves the
    current message to the specified folder. Note that the MOVE
    command deletes the message from the original folder, unlike
    the COPY command, which leaves a copy.

    If you omit the folder and file name parameters, you are prompted
    for both; if you supply only the folder name, the current Mail
    file is used and you are not prompted for the file name.

    If (after entering the MOVE command, pressing Return, and
    supplying a folder name at the prompt, but before pressing Return
    again), you decide that you do not want to move the message,
    press Ctrl/C. Ctrl/C aborts the operation and keeps you within
    Mail.
