- SEE BEGINNING INTRODUCTION Screen 1
-
- This is a Read-only file which contains an introduction to SEE. In the course
- of using this file, you will be changing it to learn how to use the editor.
- When you exit SEE, your changes will not be saved; if you come back to this
- file, it will be just like it is now. Don't be afraid of making mistakes in
- this file: you can always start over.
-
- First, the basics. In the upper-left hand corner of the screen, there is a
- flashing box. This is the cursor; it highlights the character SEE is looking at
- right now. The last line on the screen is the status line: on it, you see
- "LESSON1", which is the name of the file you are editing. Also, you see three
- numbers. The first is the number of the column you are on, the second is the
- number of the line you are on, and the last is the number of lines in this file.
-
- There are a few keys we'll talk about now. On your keyboard are four arrow
- keys, a key labeled Pg Up and a key labeled Pg Dn. The arrow keys move the
- cursor, and the page keys move the entire page. If you have a mouse, it should
- be working now: rolling the mouse will also move the cursor. Try moving the
- cursor around using the arrow keys and the mouse.
-
- To see the next page of the introduction, hit the key labeled Pg Dn once.
-

-
- About mice: Mice feel a little unusual at first. You will need about 10 minutes
- practice with your mouse before you feel comfortable with it. Be careful not
- to touch the mouse buttons; we'll get to them later. For now, just roll it
- around. In a surprisingly short time, you'll find it natural.
-
- Now we'll try some basic editing. Using either the arrow keys or the mouse,
- move the cursor so that it is on the '@' below. Now type a couple of words.
- Remember, any changes you make to this file are going to be thrown away when you
- exit, so don't worry about making mistakes. Notice that as you type, the @ is
- moved to the right to make room. If you hit the key labeled Back Space (the
- left pointing arrow above the enter key on some PC's), the character to the left
- of the cursor will disappear and all the other characters on the line will move
- over to the left. Try hitting this key a few times. This key is used to
- correct mistakes as you type.
-
- @
-
- When you're done with this, hit the key labeled Pg Up; this will take you to the
- previous page. Then hit Pg Dn to return to this page, and then Pg Dn again to
- continue with the introduction.

-
- Next, we'll try correcting some mistakes. Below on the screen, there's a line
- that says "This sentence has three mispelled wrods inn it." We're going to
- correct these three mistakes. First, "mispelled" needs another "s". Move the
- cursor so that it is on the "s" in "mispelled". Now type s. Move the cursor so
- that it is on the "r" in "wrods". Near the arrow keys on your keyboard is a key
- labeled "Del"; hit this key twice. This deletes the "r" and the "o". Now, type
- "or". Finally, move the cursor to the second "n" in "inn", and hit the delete
- key. The sentence is now repaired.
-
- This sentence has three mispelled wrods inn it.
-
- The key at the upper far left of your keyboard labeled "F1" makes lines appear
- and disappear. Hit F1 now. Notice that all the lines below the cursor moved
- down one line, and a new blank line appeared ready for you to type on. To
- remove this line, hold down the key labeled "CTRL" (near the letter "a" on your
- keyboard), and hit F1. CTRL-F1 activates the SEE command which deletes lines.
-
- Notice the "LESSON1" on the status line is now "*LESSON1". This tells you that
- the document "LESSON1" has been modified. Hit Pg Dn now.

- SEE BEGINNING INTRODUCTION Screen 4
-
- The last thing you need to know to use SEE is how to get out. If you want SEE
- to save all your changes and exit, hold down the CTRL key and hit Z. Of course,
- this particular file is marked read-only on the disk, so when SEE tries to save
- your changes, it will fail. Files must be explicitly set to read-only by the
- user: you need not worry about this accidentally happening to one of your files.
-
- If you want to exit SEE without saving any changes, hit the ESCape key, type the
- letter "a", then hold down the CTRL key and hit Z. The "a" stands for "abort".
-
- Summary of SEE introductory commands:
- move cursor mouse or arrow keys
- move up a page Pg Up
- move down a page Pg Dn
- delete a character BACK SPACE or DELETE
- open up a line F1
- remove a line CTRL-F1
- Exit (save all changes) CTRL-Z
- Exit (save no changes) ESC a CTRL-Z
-
- Hit Pg Dn now.

- SEE BEGINNING INTRODUCTION Screen 5
-
- SEE has many commands besides these; also the commands you now know have much
- more powerful forms. The mouse buttons and the other function keys all have
- more advanced functions attached to them. If this is your first time using a
- computer to edit, you already know enough to do any editing task. It is
- recommended you wait a day or two before learning more, and just practice what
- you know now until you're comfortable with it.
-
- If you have a mouse and it seems very touchy, the mouse's tail may be pulling on
- the mouse. Make sure your mouse's tail is laying loosely on your desk.
-
- The next lesson is "Lesson2"; when you're ready to learn the material in that,
- exit SEE and then type:
-
- a> SEE Lesson2
-
- To exit SEE from Lesson1, you must abort. This is because you have modified
- this file, but SEE is unable to save it to disk. To abort SEE, hit the ESC key,
- type the letter "a", and then hit CTRL-Z. When you hit the ESC key, SEE will
- display the word "Enter: " on the status line, and wait for you to type.
