CHANGE MODE

 Changes the mode for entering text---either insert or overstrike.

 Keys:  EVE Default           VT100 Keypad
        -------------------------------------
        CTRL/A or F14         CTRL/A or ENTER

 Usage notes:

 o  The mode of the buffer is shown in the status line.  To toggle the
    mode, click MB1 on the Insert or Overstrike indicator.  See help on
    Status Line.

 o  The mode of the buffer affects the following commands and keys:

       EVE Commands         EDT Keys               WPS Keypad
       ----------------     ---------------        -----------------
       DELETE (<X])         Del C   (COMMA)        Delete Char (PF4)
       ERASE CHARACTER      SpecIns (GOLD-KP3)
       QUOTE (CTRL/V)
       RESTORE CHARACTER

 o  If you use SET BOX NOPAD, the mode of the buffer determines the effects
    of some box editing operations:

       Mode          Effects with SET BOX NOPAD
       ------------------------------------------------------------
       INSERT        Cutting a box, or erasing a box selection with
                     pending delete, makes text to the right of the box
                     "collapse" to the left, closing the gap.  Pasting or
                     restoring a box pushes existing text to the right.

       OVERSTRIKE    Cutting a box, or erasing a box selection with
                     pending delete, pads the area with spaces to keep
                     the column aligment of text to the right of the box.
                     Pasting or restoring a box overwrites existing text.
                     In other words, in an overstrike-mode buffer, box
                     editing is the same as with SET BOX PAD.

    To override these effects, use either BOX CUT INSERT and BOX PASTE
    INSERT, or BOX CUT OVERSTRIKE and and BOX PASTE OVERSTRIKE.

 o  Mode is a buffer attribute---you can use insert mode in one buffer, and
    use overstrike mode in another.  For editing text, the default mode is
    insert.

 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).  See help on Editing
    Command Lines.

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