- 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.

- SEE LESSON 3 Screen 5
-
- 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.
-

-
- 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.
