NAME
    vi - a minimal screen editor

SYNOPSIS
    vi name

DESCRIPTION
    A modal, vi-flavoured VT100 screen editor. It needs a VT100-capable
    terminal (it drives the cursor with ANSI escapes) and reads keys raw
    and unbuffered, bypassing the OS line editor. The file is a flat
    buffer of fixed-width lines (about 110 lines of 80 columns). vi is a
    /bin program.

    Commands:
        h j k l    move left / down / up / right
        0  $       start / end of line
        G          last line
        i a A      insert before / after cursor / at end of line
        o          open a new line below
        x  dd      delete a character / a line
        u          undo the last change (single level)
        /pat  n    search forward for pat, repeat
        :w :q      write / quit
        :wq  :q!   write and quit / quit without saving

EXAMPLES
    vi notes.txt
    run /bin/vi.bin hello.asm
