How To: the ESC codes [Beginners Level]

Question: How do I change the text on the screen to be reversed, 
	  flashing, etc?

    This is done with [7mescape[m sequences!  An [7mescape[m sequence is a
sequence of characters, beginning with chr(27), the [7mescape[m character,
which is interpreted by the terminal to manipulate the output in
varius ways.  

    How does one create an [7mescape[m sequence?  The easiest way to create
these [7mescape[m sequences is through EDT.  To generate the <esc>
character in EDT, simply hit the [7mescape[m key "<esc>" twice.  This will
put a "<esc>" on the screen.  "<esc>" is EDT's way of representing the
[7mescape[m character. 

    EMACS is slightly different than EDT. To generate the <esc>
character in EMACS, hit control-shift-|-esc followed by an [7mescape[m
sequence.

    Some of the basic [7mescape[m sequences on the vt's and the ibm vt
emulator (kermit) are:

DESCRIPTION			[7mESCAPE[m SEQUENCE

normal text (resets text)         <esc>[0m
[1m Highlighted text[0m           <esc>[1m
[4m Underlined text[0m            <esc>[4m
[5m Flashing text [0m             <esc>[5m
[7m Reversed text [0m             <esc>[7m
#3 double size text
#4 double size text
                            	<esc>#3 and <esc>#4- both must be written
#6 double width text       	<esc>#6

 Fill screen with E's       	<esc>#8 
 Screen Blank               	<esc>[2J
 erases from cursor to
   end of line              	<esc>[K
 sets for 80 column mode    	<esc>[?3h
 sets for 132 column mode   	<esc>[?3L
 turns smooth scroll on     	<esc>[?4h
 turns smooth scroll off    	<esc>[?4l
 turns reverse video on    	<esc>[?5h
 turns reverse video off   	<esc>[?5l
 cursor home                	<esc>[?6h

 move cursor up x lines     <esc>[xA         x defaults to 1
 move cursor down x lines   <esc>[xB         x defaults to 1
 move cursor right y spaces <esc>[yC         y defaults to 1
 move cursor left y spaces  <esc>[yD         y defaults to 1
 cursor position            <esc>[y;xf       1<=y<=24   1<=x<=80
 cursor position            <esc>[y;xH       1<=y<=24   1<=x<=80

 sets scrolling between 
   A and B                  <esc>[A,Br
 toggle to graphics mode    <esc>(0
 toggle from graphics mode  <esc>(B

In the EMACS here one can type control-Q Escape (where escape is your
escape key), to insert escapes.  They are shown as ^[ in the text.

Can someone tell me how to insert a ^L using EMACS?

Does this work for anyone?  It's supposed to make `escape'      ^^^      ^^
reversed, but I'm pretty sure that news servers strip escape codes.

The last time Susan posted this guide, there was a discussion of escape codes
in Emacs.  Remember...
1) Emacs is HIGHLY customizable
2) There are different flavors of Emacs

How to insert the escape character (<esc> is the escape key on the keyboard).

Gnu Emacs    C-Q <esc>
vi           ^V ^[
UNIX shell   echo , | tr , "\033"       e.g. echo ,\(B,[0m | tr , "\033"
DOS EDIT     ^P <esc>
Macintosh    I'll ask again...any Mac users know?

Or you can make a shell script or batch file that echos the escape character.

In EMACS one can insert *any* character by typing control-Q character.
So for ^L, type ^Q ^L.
