SEE LESSON 3                           Screen 1

This file is marked Read-only so that SEE cannot alter the contents of the  disk
file.  You can always start over and the file will be just like it is now.

This lesson covers block commands.  Repeatedly throughout the lesson you will be
instructed to "click".  If you have a mouse, this means click the  mouse's  left
button.  When you click, nothing happens until you release the button.   If  you
do  not  have  a mouse, this means hold down the CTRL key and hit Q.  Ctrl-Q and
the left mouse button are equivalent.

Move  the cursor so that it is just past the 1.  (over the "^") and click (click
the left mouse button or Ctrl-Q).  Now, move the cursor so that it's on the "L",
but don't click.  Hit the delete key.  This is how SEE's block commands work.

                    1.          Leave work.
                      ^
Without moving the cursor, click again.  Move the cursor to the "." in  "work.".
Hit Open (F1).  This puts things back to the way they were.

Open,  Close,  Get,  Cut, and Delete all understand this type of argument and do
exactly what you'd expect.

                           SEE LESSON 3                           Screen 2

Move the cursor so that it's one past the "1.".  Click.  Now,  move  the  cursor
the cursor so that it's over the "G" in "Go home".  Hit Close (Ctrl-F1).  Notice
that Close deleted all the stuff inside the  indicated  rectangle.   Blocks  are
specified in SEE by 'drawing' the block's diagonal.

                    1.          Leave work.
                    2.          Stop to buy milk.
                    3.          Go home and play Trivial Pursuit.

Without moving the cursor (it should be over the "L"), click, and then move  the
cursor  so that it's on the "d" in "and play".  Hit Open (F1).  Again, this puts
things back to where they were.

Open,  Close,  Get,  Cut, and Delete all understand this type of argument and do
exactly what you would expect.

Without moving the cursor, click.  Move the cursor  so  that  it's  on  the  "G"
again, and hit Cut (Ctrl-F3).  Again, this removes the spaces.   Hit  Put  (F4).
This restores things back to the way they started.  Put knows it has a rectangle
of stuff in it's buffer.

                           SEE LESSON 3                           Screen 3

Move  the  cursor  to the "1" below and click.  Move the cursor straight down to
the  "3"  and hit Cut (Ctrl-F3).  If the rectangle has no width, SEE assumes you
mean "all these lines".

                1. Leave work.
                2. Stop to buy milk.
                3. Go home and play Trivial Pursuit.

Hit Put (F4) to restore things.  Put knows it has lines this time instead  of  a
block.  You can do exactly the same thing by using Close (Ctrl-F1)  and  Restore
(Ctrl-R).  Follow the above directions again using these commands.

Had you hit Delete instead of Cut, the same three lines would have been removed,
except there would be no way to restore them.

Hit  Home  so  that  the  cursor is at the beginning of the "1." line and click.
Notice  the  "@"  displayed  on  the  status  line;  this  tells you the file is
currently marked.  Move the cursor straight down two lines, and hit Cut.  As you
see, the result does not depend on where the zero-width rectangle is  specified.
Hit Put now to restore the lines again.

                           SEE LESSON 3                           Screen 4

Next, we'll cover SEE's replace function.  Hit Home twice to get the  cursor  to
the  upper  left  corner of the screen, and hit ESC to get the "Enter: " prompt,
and  type "apropos" (without the quotes).  Now hit Return (labeled ENTER on some
keyboards).   Notice  that  SEE  responds  with  a  diamond.  Type "Appropriate"
(again, no quotes).  Now hit Search (F10).  This is the  SEE  replace  function.
Hit  Search  (F10)  again; SEE finds and changes this "apropos".  Just as Search
remembers the last search string, Search remembers when the last  thing  it  did
was a replace.

Hit  Home  twice  to  return  to  the  top  of  the  page.   Hit  ESC,  and type
"appropriate".  Hit Return, and type "natural".  Now, hold the CTRL key down and
hit  Search  (F10).   This is SEE's global search/replace function.  Ctrl-Search
keeps going until it can't find the search string in the file again.

Finally,  we'll  cover the functions Break and Join.  Move the cursor to the "n"
in "needs" below, and hit Break (F7).  Break breaks a line in two.

              This is a line which needs splitting into two parts.

Now hit Join (Ctrl-F7).  Join joins pairs of lines together.  Leave  the  cursor
on the "n" and click.  Move the cursor to the "c" in "came" below, and hit Join.

        came from two seperate places.

Join  deletes  everything  between  the click and the activation position.  Text
removed with Join, like text removed with Delete, cannot be restored.

Move the cursor to this "X", and hit End Line (Ctrl-E or ALT-F7).

End  Line  deletes  everything  to  the right of the cursor on the current line.
text  removed  with  End  Line, like text removed with Join or Delete, cannot be
restored.








                           SEE LESSON 3                           Screen 6

Probably  by now you've tried hitting Help (Ctrl-F6).  This displays a screen of
information  to  remind  you  what commands are available.  If you wish, you may
customize  this  display  by  changing  the  file  SEE.HLP,  but  this  is   not
recommended.

Summary of the commands covered in this lesson:

    Block arguments to Open, Close, Delete, Get, Cut and Join.

    ESC "SearchText" return "ReplaceText" F10      - Replace
    ESC "SearchText" return "ReplaceText" Ctrl-F10 - Global Replace
    ESC "SearchText" return "ReplaceText" Alt-F10  - Query Replace

    Break (F7)        - Break a line into two lines.
    Join (Crtl-F7)    - Delete everything between two characters.                        between them.
    End Line (Alt-F7) - Delete to end of line.

    Help (Ctrl-F6)    - Display the file SEE.HLP
