DESCRIPTION

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

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

BUGS

31       Software tabs using ^T work only immediately after the autoindent.
32
33       Left and right shifts on intelligent terminals don't make use of insert
34       and delete character operations in the terminal.
35
36       The wrapmargin option can be fooled since it looks  at  output  columns
37       when  blanks  are  typed.  If a long word passes through the margin and
38       onto the next line without a break, then the line won't be broken.
39
40       Insert/delete within a line can be slow if tabs are present on intelli‐
41       gent terminals, since the terminals need help in doing this correctly.
42
43       Saving text on deletes in the named buffers is somewhat inefficient.
44
45       The  source command does not work when executed as :source; there is no
46       way to use the :append, :change, and :insert commands, since it is  not
47       possible  to  give  more  than one line of input to a : escape.  To use
48       these on a :global you must Q to ex command  mode,  execute  them,  and
49       then reenter the screen editor with vi or open.
