                     28: (visual) is a display oriented text editor based on

                     30: .I Ex
                     31: and
                     32: .I vi
                     33: run the same code; it is possible to get to
                     34: the command mode of
                     35: .I ex
                     36: from within
                     37: .I vi
                     38: and vice-versa.

                     53: William Joy
                     54: .br
                     55: Mark Horton added macros to \fIvisual\fR mode and is maintaining version 3
                     56: .SH BUGS
                     57: Software tabs using \fB^T\fR work only immediately after the
                     58: .I autoindent.
                     59: .PP
                     60: Left and right shifts on intelligent terminals don't make use of
                     61: insert and delete character operations in the terminal.
                     62: .PP
                     63: The
                     64: .I wrapmargin
                     65: option can be fooled since it looks at output columns when blanks are typed.
                     66: If a long word passes through the margin and onto the next line without a 
                     67: break, then the line won't be broken.
                     68: .PP
                     69: Insert/delete within a line can be slow if tabs are present on intelligent
                     70: terminals, since the terminals need help in doing this correctly.
                     71: .PP
                     72: Saving text on deletes in the named buffers is somewhat inefficient.
                     73: .PP
                     74: The
                     75: .I source
                     76: command does not work when executed as \fB:source\fR;
                     77: there is no way to use the \fB:append\fR, \fB:change\fR,
                     78: and \fB:insert\fR commands, since it is not possible to give
                     79: more than one line of input to a \fB:\fR escape.  To use these
                     80: on a \fB:global\fR you must \fBQ\fR to \fIex\fR command mode,
                     81: execute them, and then reenter the screen editor with
                     82: .I vi
                     83: or
                     84: .I open.
