SEE LESSON 2 Screen 1

People editing files often wish to get a copy of some lines and place them
somewhere. SEE has an advanced facility for accomplishing this. Move the
cursor to the line that says "This is the second line.", and hit the function
Get (F3). This tells SEE to make an internal copy of the current line. Now hit
Close (CTRL-F1) to remove this line. Finally, hit the down arrow key so that
the cursor is one line below the "first line", and hit Put (F4).

This is the second line.
This is the first line.

Throughout these lessons, the commands are accessed through the function keys.
You can also access the commands by poping up the menu (hit "*" on your numeric
keypad) and selecting the command you want. You can move around the menus using
your mouse or arrow keys. To select a menu item, hit ENTER, or keypad "*", or
the left mouse button. To get out of the menus without selecting, hit Escape.

SEE still has the "second line" in its internal buffer; if you were to hit Put
again, SEE would place another identical copy into the file. Let's put the
lines back the way they were before. Move the cursor up one line to the "first
line", and hit Get (F3) followed by Close (CTRL-F1). Move the cursor down one
line, and hit Put (F4). The lines should be upside-down again.

SEE LESSON 2 Screen 2

Now, we'll do exactly the same thing as before, but using different SEE
commands. Move the cursor to the "second line", and hit Cut (CTRL-F3). Cut is
exactly the same as Get followed immediately by Close. Move the cursor up one
line and hit Put (F4).

This is the second line.
This is the first line.
This is the third line.

Get, Cut, Put, and Paste (which we haven't tried yet) all share the same buffer.
If you hit Cut or Get and there is already something in the buffer, the stuff in
the buffer is discarded. Hit Put again. As was mentioned earlier, SEE still
has the same line in its buffer. Hit Cut to get rid of this line.

Paste is like Put, but it places the line on top of whatever is already there.
Move the cursor up one line, and hit Paste.

F3, CTRL-F3, F4, and CTRL-F4 are also accessed by popping up the menu (hitting
keypad "*"), moving sideways to "Move&Copy", down to the appropriate command,
and selecting (ENTER, mouse left, or keypad *).


SEE LESSON 2 Screen 3

SEE has a few simple commands for moving around the screen quickly. These are:

TAB - The TAB key moves you forward to the next tab stop, just
like a typewriter. Tab stops are every four columns.

CTRL-U - Moves you backwards to the previous tab stop.

CTRL-Arrow - Holding the control key down while pressing the left or
right arrow key moves eight spaces instead of one.

HOME - Moves the cursor to the beginning of the line. If you
are already at the beginning of the line, HOME moves
you to the beginning of the first line on the screen.

END - Moves you to the end of the line. If you are already at
the end of the line, END moves you to the end of the
last line on the screen.

Try each of these commands a few times.

SEE LESSON 2 Screen 4

Similarly, SEE has a few commands to move you quickly through a file.

CTRL-PG - Holding the control key down while hitting PG UP or
PG DN moves you four pages instead of one.

CTRL-HOME - Holding the control key down while hitting HOME moves
you to the beginning of the file.

CTRL-END - Holding the control key down while hitting END moves
you to the last line of the file.

Generally speaking, if a key near the arrow keys does something, using Ctrl with
that key does more of the same. Moving commands are under menu header "Display".

On the lower right corner of the screen, there are three numbers. The first is
the current column, the second is the current line number, and the third is the
number of lines in the file. This can help if you get lost.

Try each of these commands now. Remember to get yourself back to Screen 5 when
you're done trying them out...

SEE LESSON 2 Screen 5

The next command we'll cover is Search. Hit HOME twice so that the cursor is at
the upper left corner of the screen. At the bottom of the screen is the word
"apropos"; we will search for this word. Hit the key labeled ESC. The cursor
will jump down to the status line, and the word "Enter: " will appear. Now,
type the word "apropos" (without the quotes). Hit Search (the "+" key on the
numeric keypad or menu choice Search-k+). The word "Enter: " and your input will
disappear, and the cursor will jump to the first occurance the word, which is on
line 3 of this paragraph. Hit Search (keypad "+") again immediately; the cursor
will jump to the second occurance, which is on line 5 of this paragraph. Search
remembers what it was searching for, and does it again. Now hit Search again.
The cursor will jump to the last occurance (below). If you hit Search again,
SEE reports "Search: string not found". The keypad "-" key searches backwards.

Apropos

Finally, the insert key. Move the cursor right one space, and insert a second
"p". Now hit the insert key (INS), move the cursor right so that it is
underlining the second "o", and type "riate". Notice that the cursor turned
into an underscore to flag this change in behavior. Hit the insert key again;

now things are back to normal. Insert mode is under menu header "Options".

Summary of the commands covered in this lesson:

Get (F3) - Get a copy of the current line
Cut (Ctrl-F3) - Cut the current line out of the file
Put (F4) - Put something previously Get or Cut into the file
TAB - Move to the next tab stop.
CTRL-U - Move to the previous tab stop.
HOME - Move to the beginning of the line.
END - Move to the end of the line.
CTRL-Arrow - Move left or right 8 spaces.
CTRL-PG - Move up or down 4 pages.
CTRL-HOME - Move to the beginning of the file.
CTRL-END - Move to the end of the file.
INS - Change inserting characters to/from overwriting characters.
ESC "text" Search (keypad "+") - Search forward for "text".
ESC "text" Search (keypad "-") - Search backward for "text".

You have now learned about half the commands in SEE.
