INTRODUCTION
                               TO THE VI EDITOR

The software package "vi" has two modes of operation, command mode (for
entering commands) and text mode (for entering text).

You enter command mode by touching the ESC key (if you are already in command
mode, your terminal will beep at you).

There is a visual indication that you are in text mode on the right-hand side
at the bottom of the current window ("INSERT MODE", "APPEND MODE", or "REPLACE
MODE").

Starting the editor:

  vi filename

All the commands listed below require you to be in command mode.  Commands may
be several characters long.

Controlling an editing session:

  :w <return>     (save all changes to disk)
  :wq <return>    (save all changes to disk and exit the editor)
  :q! <return>    (exit the editor without saving any changes)

Cursor Movement:

  up arrow     or  k    (move up one line)
  down arrow   or  j    (move down one line)
  left arrow   or  h    (move left one character)
  right arrow  or  l    (move right one character)

  ctrl f    (next screen)
  ctrl d    (next half screen)
  ctrl b    (previous screen)
  ctrl u    (previous half screen)

  H     (top of screen)
  L     (bottom of screen)
  0     (start of line)
  $     (end of line)
  G     (last line)
  nG    (go to line n)

Text Operations:

  x     (delete one character at cursor position)
  D     (delete from cursor position to end of line)
  dd    (delete entire line)
  r     (replace character at cursor position by next character entered)
  R     (replace characters until ESC is entered)
  i     (insert characters to left of cursor position until ESC is entered)
  a     (insert characters to right of cursor position until ESC is entered)
  o     (create a blank line below current line and enter text mode)
  J     (append the line below to the end of the current line)
