!   GNU Emacs uses an extension of the ASCII character set for keyboard
  input; it also accepts non-character input events including function
  keys and mouse button actions.
  
!   ASCII consists of 128 character codes.  Some of these codes are
  assigned graphic symbols such as @samp{a} and @samp{=}; the rest are
  control characters, such as @kbd{Control-a} (usually written @kbd{C-a}
  for short).  @kbd{C-a} gets its name from the fact that you type it by
  holding down the @key{CTRL} key while pressing @kbd{a}.
  
!   Some ASCII control characters have special names, and most terminals
  have special keys you can type them with: for example, @key{RET},
  @key{TAB}, @key{DEL} and @key{ESC}.  The space character is usually
  referred to below as @key{SPC}, even though strictly speaking it is a
  graphic character whose graphic happens to be blank.  Some keyboards
  have a key labeled ``linefeed'' which is an alias for @kbd{C-j}.
  
!   Emacs extends the ASCII character set with thousands more printing
  characters (@pxref{International}), additional control characters, and a
  few more modifiers that can be combined with any character.
  
!   On ASCII terminals, there are only 32 possible control characters.
  These are the control variants of letters and @samp{@@[]\^_}.  In
  addition, the shift key is meaningless with control characters:

  @cindex characters (in text)
  
    Text in Emacs buffers is a sequence of 8-bit bytes.  Each byte can
! hold a single ASCII character.  Both ASCII control characters (octal
! codes 000 through 037, and 0177) and ASCII printing characters (codes
! 040 through 0176) are allowed; however, non-ASCII control characters
  cannot appear in a buffer.  The other modifier flags used in keyboard
  input, such as Meta, are not allowed in buffers either.
  
!   Some ASCII control characters serve special purposes in text, and have
  special names.  For example, the newline character (octal code 012) is
  used in the buffer to end a line, and the tab character (octal code 011)
  is used for indenting to the next tab stop column (normally every 8
  columns).  @xref{Text Display}.
  
!   Non-ASCII printing characters can also appear in buffers.  When
! multibyte characters are enabled, you can use any of the non-ASCII
  printing characters that Emacs supports.  They have character codes
  starting at 256, octal 0400, and each one is represented as a sequence
  of two or more bytes.  @xref{International}.  Single-byte characters
  with codes 128 through 255 can also appear in multibyte buffers.
  
    If you disable multibyte characters, then you can use only one
! alphabet of non-ASCII characters, but they all fit in one byte.  They
  use codes 0200 through 0377.  @xref{Single-Byte Character Support}.
