1      The Emacs text editor is designed specifically for video display
 2 terminals.  It automatically displays as much of a "segment" as will fit on the
 3 screen and enables you to move the "cursor" to any point in the text.  At the
 4 location of the cursor you can add, erase, and change text much as you do when
 5 writing and erasing on paper.  You see the effects of your editing as you
 6 type.

 8      The functions of editing are directed by "requests" that you execute by
 9 using the ESCAPE and the CONTROL keys.  Almost all of the requests are made
10 with one or the other or both of these two keys.  The requests themselves are
11 not displayed on the screen, though.  In addition, Emacs has a macro facility
12 that enables you to combine a number of requests and execute them all at once.
13 Macros can also be saved.

15      Emacs also lets you work on several segments at the same time.  It does
16 this by keeping segments in separate buffers that you move between by
17 issuing requests.  This is handy for comparing different segments and
18 inserting text from one segment into another.
