  CHANGE MODE

  Changes the mode for entering text in---either insert or overstrike---as
  shown in the status line.

  Key:   EVE default        VT100 keypad
         ----------------------------------
         CTRL/A or F14      CTRL/A or ENTER

  Usage notes:

  o  The mode of the buffer also affects commands or keys that add or erase
     a single character such as DELETE, ERASE CHARACTER, QUOTE, and RESTORE
     CHARACTER.

  o  If you use SET BOX NOPAD, the mode of the buffer affects box editing as
     follows:

     Mode of buffer    Effects with SET BOX NOPAD
     ------------------------------------------------------------------
     INSERT            Cutting a box makes text to the right of the
                       box "collapse" to the left, closing the gap.
                       Pasting a box pushes existing text to the right.

     OVERSTRIKE        Cutting a box pads the area with spaces to keep
                       the column alignment of text to the right of the
                       box.  Pasting a box overwrites existing text.
                       Thus, in overstrike mode, box editing is the same
                       as with SET BOX PAD, which is the default setting.

  o  To override these effects without changing your settings, use either
     BOX CUT INSERT and BOX PASTE INSERT, or BOX CUT OVERSTRIKE and BOX
     PASTE OVERSTRIKE.

  o  Mode is a buffer attribute---you can use insert mode in one buffer and
     use overstrike mode in another. Default is INSERT MODE.

  o  For typing or editing EVE command lines, the mode matches your terminal
     setting. To change the mode when you are editing a command line, press
     a key defined as CHANGE MODE (such as CTRL/A)---effectively, changing
     the mode of the COMMANDS buffer or $PROMPTS$ buffer. See help on
     Editing Command Lines.

  o  To change the mode of an unmodifiable buffer, first use the command SET
     BUFFER MODIFIABLE.

  o  If your system has a mouse, you can toggle the mode of the buffer by
     clicking M1 on the Insert or Overstrike indicator in the status line.
     This works on DECwindows, DECterm, or UIS. See help on Status Line.
