TEXT  -  continue typing the message

Usage:  TEXT

The TEXT command lets you type more text at the end of the outgoing message.
  The cursor is placed at the end of the existing text.
 
TEXT may be used when you have typed ESC by mistake, or have DISPLAYed
  the message and decided to add more, or have used RESTORE-DRAFT to
  continue a message started earlier.  The EDIT command is similar, but 
  uses the editor (default is emacs) instead.

Example:
    Send>text
    [control-k to redisplay existing text]
