NAME
       vi - screen oriented (visual) display editor based on ex

SYNOPSIS
       vi [ -t tag ] [ -r ] [ +command ] [ -l ] [ -wn ] name ...

DESCRIPTION
       Vi  (visual)  is a display oriented text editor based on ex(1).  Ex and
       vi run the same code; it is possible to get to the command mode  of  ex
       from within vi and vice-versa.

       The  Vi  Quick  Reference  card and the Introduction to Display Editing
       with Vi provide full details on using vi.

FILES

BUGS
       Software tabs using ^T work only immediately after the autoindent.

       Left and right shifts on intelligent terminals don’t make use of insert
       and delete character operations in the terminal.

       The wrapmargin option can be fooled since it looks  at  output  columns
       when  blanks  are  typed.  If a long word passes through the margin and
       onto the next line without a break, then the line won’t be broken.

       Insert/delete within a line can be slow if tabs are present on intelli‐
       gent  terminals, since the terminals need help in doing this correctly.

       Saving text on deletes in the named buffers is somewhat inefficient.

       The source command does not work when executed as :source; there is  no
       way  to use the :append, :change, and :insert commands, since it is not
       possible to give more than one line of input to a  :  escape.   To  use
       these  on  a  :global  you must Q to ex command mode, execute them, and
       then reenter the screen editor with vi or open.
