idlwave: Syntax Highlighting

 
 4.1.5 Syntax Highlighting
 -------------------------
 
 Highlighting of keywords, comments, strings etc. can be accomplished
 with ‘font-lock’.  If you are using ‘global-font-lock-mode’ (in Emacs),
 or have ‘font-lock’ turned on in any other buffer in XEmacs, it should
 also automatically work in IDLWAVE buffers.  If you’d prefer invoking
 font-lock individually by mode, you can enforce it in ‘idlwave-mode’
 with the following line in your ‘.emacs’:
 
      (add-hook 'idlwave-mode-hook 'turn-on-font-lock)
 
 IDLWAVE supports 3 increasing levels of syntax highlighting.  The
 variable ‘font-lock-maximum-decoration’ determines which level is
 selected.  Individual categories of special tokens can be selected for
 highlighting using the variable ‘idlwave-default-font-lock-items’.
 
  -- User Option: idlwave-default-font-lock-items
      Items which should be fontified on the default fontification level
