     Vim is a very powerful editor that has many commands, too many to
     explain in a tutor such as this.  This tutor is designed to describe
     enough of the commands that you will be able to easily use Vim as
     an all-purpose editor.

     The approximate time required to complete the tutor is 25-30 minutes,
     depending upon how much time is spent with experimentation.

     The commands in the lessons will modify the text.  Make a copy of this
     file to practise on (if you started "vimtutor" this is already a copy).

     It is important to remember that this tutor is set up to teach by
     use.  That means that you need to execute the commands to learn them
     properly.  If you only read the text, you will forget the commands!

     Now, make sure that your Shift-Lock key is NOT depressed and press
     the   j   key enough times to move the cursor so that Lesson 1.1
     completely fills the screen.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            Lesson 1.1:  MOVING THE CURSOR


   ** To move the cursor, press the h,j,k,l keys as indicated. **
         ^
         k            Hint:  The h key is at the left and moves left.
       < h     l >           The l key is at the right and moves right.
         j               The j key looks like a down arrow
         v
  1. Move the cursor around the screen until you are comfortable.

  2. Hold down the down key (j) until it repeats.
---> Now you know how to move to the next lesson.

  3. Using the down key, move to Lesson 1.2.

Note: If you are ever unsure about something you typed, press <ESC> to place
      you in Normal mode.  Then retype the command you wanted.

Note: The cursor keys should also work.  But using hjkl you will be able to
      move around much faster, once you get used to it.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
             Lesson 1.2: ENTERING AND EXITING VIM


  !! NOTE: Before executing any of the steps below, read this entire lesson!!

  1. Press the <ESC> key (to make sure you are in Normal mode).

  2. Type:            :q! <ENTER>.

---> This exits the editor WITHOUT saving any changes you have made.
     If you want to save the changes and exit type:
                :wq  <ENTER>

  3. When you see the shell prompt, type the command that got you into this
     tutor.  That could be:    vimtutor <ENTER>
     Normally you would use:    vim tutor <ENTER>

---> 'vim' means enter the vim editor, 'tutor' is the file you wish to edit.

  4. If you have these steps memorized and are confident, execute steps
     1 through 3 to exit and re-enter the editor.  Then move the cursor down
     to Lesson 1.3.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
             Lesson 1.3: TEXT EDITING - DELETION

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                   LESSON 1 SUMMARY


  1. The cursor is moved using either the arrow keys or the hjkl keys.
     h (left)    j (down)       k (up)        l (right)

  2. To enter Vim (from the % prompt) type:  vim FILENAME <ENTER>

  3. To exit Vim type:       <ESC>   :q!     <ENTER>  to trash all changes.

  4. To delete a character under the cursor in Normal mode type:  x

  5. To insert text at the cursor while in Normal mode type:
     i     type in text    <ESC>

NOTE: Pressing <ESC> will place you in Normal mode or will cancel
      an unwanted and partially completed command.

Now continue with Lesson 2.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            Lesson 2.1: DELETION COMMANDS


        ** Type  dw  to delete to the end of a word. **

  5. Move on to Lesson 2.3 to understand what is happening.





~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
             Lesson 2.3: ON COMMANDS AND OBJECTS


  The format for the  d  delete command is as follows:

     [number]   d    object        OR         d     [number]   object
  Where:
    number - is how many times to execute the command (optional, default=1).
    d - is the command to delete.
    object - is what the command will operate on (listed below).

  A short list of objects:
    w - from the cursor to the end of the word, including the space.
    e - from the cursor to the end of the word, NOT including the space.
    $ - from the cursor to the end of the line.

NOTE:  For the adventurous, pressing just the object while in Normal mode
       without a command will move the cursor as specified in the object list.




~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Lesson 2.4: AN EXCEPTION TO  'COMMAND-OBJECT'


           ** Type     dd   to delete a whole line. **

  Due to the frequency of whole line deletion, the designers of Vi decided
  it would be easier to simply type two d's in a row to delete a line.

  1. Move the cursor to the second line in the phrase below.
  2. Type  dd  to delete the line.
  3. Now move to the fourth line.
  4. Type   2dd   (remember  number-command-object) to delete the two lines.

  1. Move the cursor to the line below marked ---> and place it on the
     first error.
  2. Type  x  to delete the first unwanted character.
  3. Now type  u  to undo the last command executed.
  4. This time fix all the errors on the line using the  x  command.
  5. Now type a capital  U  to return the line to its original state.
  6. Now type  u  a few times to undo the  U  and preceding commands.
  7. Now type CTRL-R (keeping CTRL key pressed while hitting R) a few times
     to redo the commands (undo the undo's).

---> Fiix the errors oon thhis line and reeplace them witth undo.

  8. These are very useful commands.  Now move on to the Lesson 2 Summary.

---> This line has a few words that need changing using the change command.

Notice that  cw  not only replaces the word, but also places you in insert.



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
               Lesson 3.4: MORE CHANGES USING c


     ** The change command is used with the same objects as delete. **

  1. The change command works in the same way as delete.  The format is:

       [number]   c   object       OR        c    [number]   object

  4. The format for change is:

     [number]   c    object          OR    c   [number]   object

Now go on to the next lesson.



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
             Lesson 4.1: LOCATION AND FILE STATUS


  ** Type CTRL-g to show your location in the file and the file status.
     Type SHIFT-G to move to a line in the file. **

  Note: Read this entire lesson before executing any of the steps!!

  1. Hold down the Ctrl key and press  g .  A status line will appear at the
     bottom of the page with the filename and the line you are on.  Remember
     the line number for Step 3.

  2. Press shift-G to move you to the bottom of the file.

  3. Type in the number of the line you were on and then shift-G.  This will
     return you to the line you were on when you first pressed Ctrl-g.
     (When you type in the numbers, they will NOT be displayed on the screen.)

  4. If you feel confident to do this, execute steps 1 through 3.



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            Lesson 4.2: THE SEARCH COMMAND


     ** Type  /  followed by a phrase to search for the phrase. **

  1. In Normal mode type the  /  character.  Notice that it and the cursor
     appear at the bottom of the screen as with the  :    command.

  3. To search for the same phrase again, simply type  n .
     To search for the same phrase in the opposite direction, type  Shift-N .

  4. If you want to search for a phrase in the backwards direction, use the
     command  ?  instead of /.

---> "errroor" is not the way to spell error;  errroor is an error.

Note: When the search reaches the end of the file it will continue at the
      start.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
           Lesson 4.3: MATCHING PARENTHESES SEARCH

     This changes all occurrences on the line.

---> thee best time to see thee flowers is in thee spring.

  4. To change every occurrence of a character string between two lines,
     type   :#,#s/old/new/g    where #,# are the numbers of the two lines.
     Type   :%s/old/new/g    to change every occurrence in the whole file.




~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                   LESSON 4 SUMMARY


  1. Ctrl-g  displays your location in the file and the file status.
     Shift-G  moves to the end of the file.  A line number followed
     by  Shift-G  moves to that line number.

  2. Typing  /    followed by a phrase searches FORWARD for the phrase.
     Typing  ?    followed by a phrase searches BACKWARD for the phrase.
     After a search type  n  to find the next occurrence in the same direction
     or  Shift-N  to search in the opposite direction.

  3. Typing  %    while the cursor is on a  (,),[,],{, or }  locates its
     matching pair.

  4. To substitute new for the first old on a line type    :s/old/new
     To substitute new for all 'old's on a line type       :s/old/new/g
     To substitute phrases between two line #'s type       :#,#s/old/new/g
     To substitute all occurrences in the file type       :%s/old/new/g
     To ask for confirmation each time add 'c'           :%s/old/new/gc


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Lesson 5.1: HOW TO EXECUTE AN EXTERNAL COMMAND


   ** Type  :!    followed by an external command to execute that command. **

  1. Type the familiar command    :  to set the cursor at the bottom of the
     screen.  This allows you to enter a command.

  2. Now type the  !  (exclamation point) character.  This allows you to
     execute any external shell command.

  3. As an example type   ls   following the ! and then hit <ENTER>.  This
     will show you a listing of your directory, just as if you were at the
     shell prompt.  Or use   :!dir  if ls doesn't work.

Note:  It is possible to execute any external command this way.

Note:  All  :  commands must be finished by hitting <ENTER>




~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              Lesson 5.2: MORE ON WRITING FILES


     ** To save the changes made to the file, type  :w FILENAME. **

  1. Type  :!dir  or  :!ls  to get a listing of your directory.
     You already know you must hit <ENTER> after this.

  2. Choose a filename that does not exist yet, such as TEST.

  3. Now type:     :w TEST   (where TEST is the filename you chose.)

  4. This saves the whole file    (Vim Tutor)  under the name TEST.
     To verify this, type    :!dir   again to see your directory

Note: If you were to exit Vim and enter again with the filename TEST, the file
      would be an exact copy of the tutor when you saved it.

  5. Now remove the file by typing (MS-DOS):    :!del TEST
                or (Unix):    :!rm TEST


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            Lesson 5.3: A SELECTIVE WRITE COMMAND


    ** To save part of the file, type   :#,# w FILENAME **

  1. Once again, type  :!dir  or  :!ls  to obtain a listing of your directory
     and choose a suitable filename such as TEST.

  2. Move the cursor to the top of this page and type  Ctrl-g  to find the
     number of that line.  REMEMBER THIS NUMBER!

  3. Now move to the bottom of the page and type  Ctrl-g again.  REMEMBER THIS
     LINE NUMBER ALSO!

  4. To save ONLY a section to a file, type   :#,# w TEST   where #,# are
     the two numbers you remembered (top,bottom) and TEST is your filename.

  5. Again, see that the file is there with  :!dir  but DO NOT remove it.




~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
           Lesson 5.4: RETRIEVING AND MERGING FILES


       ** To insert the contents of a file, type   :r FILENAME **

  1. Type   :!dir   to make sure your TEST filename is present from before.

  2. Place the cursor at the top of this page.

NOTE:  After executing Step 3 you will see Lesson 5.3.    Then move DOWN to
       this lesson again.

  3. Now retrieve your TEST file using the command   :r TEST   where TEST is
     the name of the file.

NOTE:  The file you retrieve is placed starting where the cursor is located.

  4. To verify that a file was retrieved, cursor back and notice that there
     are now two copies of Lesson 5.3, the original and the file version.



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                   LESSON 5 SUMMARY


  1.  :!command  executes an external command.

      Some useful examples are:
     (MS-DOS)      (Unix)
      :!dir           :!ls           -  shows a directory listing.
      :!del FILENAME   :!rm FILENAME   -  removes file FILENAME.

  2.  :w FILENAME  writes the current Vim file to disk with name FILENAME.

  3.  :#,#w FILENAME  saves the lines # through # in file FILENAME.

  4.  :r FILENAME  retrieves disk file FILENAME and inserts it into the
      current file following the cursor position.






~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
             Lesson 6.1: THE OPEN COMMAND


 ** Type  o  to open a line below the cursor and place you in Insert mode. **

  1. Move the cursor to the line below marked --->.

  2. Type  o (lowercase) to open up a line BELOW the cursor and place you in
     Insert mode.

  3. Now copy the line marked ---> and press <ESC> to exit Insert mode.

---> After typing  o  the cursor is placed on the open line in Insert mode.

  4. To open up a line ABOVE the cursor, simply type a capital    O , rather
     than a lowercase  o.  Try this on the line below.
Open up a line above this by typing Shift-O while the cursor is on this line.





~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            Lesson 6.2: THE APPEND COMMAND


         ** Type  a  to insert text AFTER the cursor. **

  1. Move the cursor to the end of the first line below marked ---> by
     typing  $    in Normal mode.

  2. Type an  a  (lowercase) to append text AFTER the character under the
     cursor.  (Uppercase  A  appends to the end of the line.)

Note: This avoids typing  i , the last character, the text to insert, <ESC>,
      cursor-right, and finally, x , just to append to the end of a line!

  3. Now complete the first line.  Note also that append is exactly the same
     as Insert mode, except for the location where text is inserted.

---> This line will allow you to practice
---> This line will allow you to practice appending text to the end of a line.



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            Lesson 6.3: ANOTHER VERSION OF REPLACE


      ** Type a capital  R  to replace more than one character. **

  1. Move the cursor to the first line below marked --->.

  2. Place the cursor at the beginning of the first word that is different
     from the second line marked ---> (the word 'last').

  3. Now type  R  and replace the remainder of the text on the first line by
     typing over the old text to make the first line the same as the second.

---> To make the first line the same as the last on this page use the keys.
---> To make the first line the same as the second, type R and the new text.

  4. Note that when you press <ESC> to exit, any unaltered text remains.





~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                Lesson 6.4: SET OPTION

      ** Set an option so a search or substitute ignores case **

  1. Search for 'ignore' by entering:
     /ignore
     Repeat several times by hitting the n key

  2. Set the 'ic' (Ignore case) option by typing:
     :set ic

  3. Now search for 'ignore' again by entering: n
     Repeat search several more times by hitting the n key

  4. Set the 'hlsearch' and 'incsearch' options:
     :set hls is

  5. Now enter the search command again, and see what happens:
     /ignore

  6. To remove the highlighting of matches, type:
     :nohlsearch
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                   LESSON 6 SUMMARY


  1. Typing  o    opens a line BELOW the cursor and places the cursor on the open
     line in Insert mode.
     Typing a capital  O  opens the line ABOVE the line the cursor is on.

  2. Type an  a  to insert text AFTER the character the cursor is on.
     Typing a capital  A  automatically appends text to the end of the line.

  3. Typing a capital  R  enters Replace mode until  <ESC>  is pressed to exit.

  4. Typing ":set xxx" sets the option "xxx"









~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
               LESSON 7: ON-LINE HELP COMMANDS


              ** Use the on-line help system **

  Vim has a comprehensive on-line help system.  To get started, try one of
  these three:
    - press the <HELP> key (if you have one)
    - press the <F1> key (if you have one)
    - type   :help <ENTER>

  Type   :q <ENTER>   to close the help window.

  You can find help on just about any subject, by giving an argument to the
  ":help" command.  Try these (don't forget pressing <ENTER>):

    :help w
    :help c_<T
    :help insert-index
    :help user-manual

               LESSON 8: CREATE A STARTUP SCRIPT

              ** Switch on Vim features **

  Vim has many more features than Vi, but most of them are disabled by default.
  To start using more features you have to create a "vimrc" file.

  1. Start editing the "vimrc" file, this depends on your system:
    :edit ~/.vimrc            for Unix
    :edit $VIM/_vimrc        for MS-Windows

  2. Now read the example "vimrc" file text:

    :read $VIMRUNTIME/vimrc_example.vim

  3. Write the file with:

    :write

  The next time you start Vim it will use syntax highlighting.
  You can add all your preferred settings to this "vimrc" file.

  This concludes the Vim Tutor.  It was intended to give a brief overview of
  the Vim editor, just enough to allow you to use the editor fairly easily.
  It is far from complete as Vim has many many more commands.  Read the user
  manual next: ":help user-manual".
