(emacs.info) Faces

 
 Using Multiple Typefaces
 ========================
 
    When using Emacs with X, you can set up multiple styles of displaying
 characters.  The aspects of style that you can control are the type
 font, the foreground color, the background color, and whether to
 underline.  Emacs on MS-DOS supports faces partially by letting you
 control the foreground and background colors of each face (
 MS-DOS).
 
    The way you control display style is by defining named "faces".
 Each face can specify a type font, a foreground color, a background
 color, and an underline flag; but it does not have to specify all of
 them.  Then by specifying the face or faces to use for a given part of
 the text in the buffer, you control how that text appears.
 
    The style of display used for a given character in the text is
 determined by combining several faces.  Any aspect of the display style
 that isn't specified by overlays or text properties comes from the frame
 itself.
 
    Enriched mode, the mode for editing formatted text, includes several
 commands and menus for specifying faces.   Format Faces, for how
 to specify the font for text in the buffer.   Format Colors, for
 how to specify the foreground and background color.
 
    To alter the appearance of a face, use the customization buffer.
  Face Customization.  You can also use X resources to specify
 attributes of particular faces ( Resources X).
 
    To see what faces are currently defined, and what they look like,
 type `M-x list-faces-display'.  It's possible for a given face to look
 different in different frames; this command shows the appearance in the
 frame in which you type it.  Here's a list of the standardly defined
 faces:
 
 `default'
      This face is used for ordinary text that doesn't specify any other
      face.
 
 `modeline'
      This face is used for mode lines.  By default, it's set up as the
      inverse of the default face.   Display Vars.
 
 `highlight'
      This face is used for highlighting portions of text, in various
      modes.
 
 `region'
      This face is used for displaying a selected region (when Transient
      Mark mode is enabled--see below).
 
 `secondary-selection'
      This face is used for displaying a secondary selection (
      Secondary Selection).
 
 `bold'
      This face uses a bold variant of the default font, if it has one.
 
 `italic'
      This face uses an italic variant of the default font, if it has
      one.
 
 `bold-italic'
      This face uses a bold italic variant of the default font, if it
      has one.
 
 `underline'
      This face underlines text.
 
    When Transient Mark mode is enabled, the text of the region is
 highlighted when the mark is active.  This uses the face named
 `region'; you can control the style of highlighting by changing the
 style of this face ( Face Customization).   Transient
 Mark, for more information about Transient Mark mode and activation
 and deactivation of the mark.
 
    One easy way to use faces is to turn on Font Lock mode.  This minor
 mode, which is always local to a particular buffer, arranges to choose
 faces according to the syntax of the text you are editing.  It can
 recognize comments and strings in most languages; in several languages,
 it can also recognize and properly highlight various other important
 constructs.   Font Lock, for more information about Font Lock
 mode and syntactic highlighting.
 
    You can print out the buffer with the highlighting that appears on
 your screen using the command `ps-print-buffer-with-faces'.
