 3 Controlling Screen Display
 ****************************
 
 It is often desirable to get visual help of what markup code in a text
 actually does without having to decipher it explicitly.  For this
 purpose Emacs and AUCTeX provide font locking (also known as syntax
 highlighting) which visually sets off markup code like macros or
 environments by using different colors or fonts.  For example text to be
 typeset in italics can be displayed with an italic font in the editor as
 well, or labels and references get their own distinct color.
 
    While font locking helps you grasp the purpose of markup code and
 separate markup from content, the markup code can still be distracting.
 AUCTeX lets you hide those parts and show them again at request with its
 built-in support for hiding macros and environments which we call
 folding here.
 
    Besides folding of macros and environments, AUCTeX provides support
 for Emacs' outline mode which lets you narrow the buffer content to
 certain sections of your text by hiding the parts not belonging to these
 sections.
 
    Moreover, you can focus in a specific portion of the code by
 narrowing the buffer to the desired region.  AUCTeX provides also
 functions to narrow the buffer to the current group and to LaTeX
 environments.
 
    AUCTeX also provides some WYSIWYG features.
 
    First, you can customize 'font-latex-fontify-script' to enable
 special formatting of '^' superscripts and '_' subscripts (Font
 Locking).
 
    Secondly, AUCTeX with GNU Emacs 25 or later can display certain math
 macros using Unicode characters, e.g., '\alpha' as α.  This is called
 prettification and is lightweight and reasonable robust (
 Prettifying).
 
    A more accurate approach is provided by preview-latex, a subsystem of
 AUCTeX, see Introduction (preview-latex)Top.  This system uses
 LaTeX to generate images that are then displayed in your buffer.  It is
 extremely accurate but can be fragile with some packages (like older pgf
 versions).
 
    Please note that you can use prettification and preview-latex
 together.
