Emacs commands generally involve the CONTROL key (sometimes labelled CTRL or CTL)
or the META key (sometimes labelled ESC or EDIT). Rather than write out META or
CONTROL each time we want you to prefix a character, we'll use the following  
abbreviations:   C- means hold the CONTROL key while typing the character   Thus,  
C-f would be: hold the CONTROL key and type f.   M-   means hold the META or EDIT  
key down while typing . If there is no META or EDIT key, type , release it, then  
type the character . "" stands for the key labelled "ALT" or "ESC". Important  
note: to end the Emacs session, type C-x C-c. (Two characters.) The characters "  
>> " at the left margin indicate directions for you to try using a command. For  
instance:
>> Now type C-v (View next screen) to move to the next screen. (go ahead, do it  
by depressing the control key and v together). From now on, you'll be expected to  
do this whenever you finish reading the screen.
Note that there is an overlap when going from screen to screen; this provides  
some continuity when moving through the file.
The first thing that you need to know is how to move around from place to place  
in the file. You already know how to move forward a screen, with C-v. To move  
backwards a screen, type M-v (depress the META key and type v, or type v if you  
don't have a META or EDIT key).
>> Try typing M-v and then C-v to move back and forth a few times.
