U. Editing Programs

Emacs provides many features to facilitate editing programs. Some of these features can

• Find or move over top-level definitions (see section U.2 Top-Level Definitions, or Defuns).
• Apply the usual indentation conventions of the language (see section U.3 Indentation for Programs).
• Insert, kill or align comments (see section U.5 Manipulating Comments).
• Balance parentheses (see section U.4 Commands for Editing with Parentheses).
• Highlight program syntax (see section J.2 Font Lock mode).
