Minor Modes
***********

   CC Mode contains two minor-mode-like features that you should find
useful while you enter new C code.  The first is called "auto-newline"
mode, and the second is called "hungry-delete" mode.  These minor modes
can be toggled on and off independently, and CC Mode can be configured
so that it starts up with any combination of these minor modes.  By
default, both of these minor modes are turned off.

   The state of the minor modes is always reflected in the minor mode
list on the modeline of the CC Mode buffer.  When auto-newline mode is
enabled, you will see `C/a' on the mode line (1).  When hungry delete
mode is enabled you would see `C/h' and when both modes are enabled,
you'd see `C/ah'.

   CC Mode provides key bindings which allow you to toggle the minor
modes on the fly while editing code.  To toggle just the auto-newline
state, hit `C-c C-a' (`c-toggle-auto-state').  When you do this, you
should see the `a' indicator either appear or disappear on the
modeline.  Similarly, to toggle just the hungry-delete state, use `C-c
C-d' (`c-toggle-hungry-state'), and to toggle both states, use `C-c
C-t' (`c-toggle-auto-hungry-state').

   To set up the auto-newline and hungry-delete states to your preferred
values, you would need to add some lisp to your `.emacs' file that
called one of the `c-toggle-*-state' functions directly.  When called
programmatically, each function takes a numeric value, where a positive
number enables the minor mode, a negative number disables the mode, and
zero toggles the current state of the mode.

   So for example, if you wanted to enable both auto-newline and
hungry-delete for all your C file editing, you could add the following
to your `.emacs' file:

     (add-hook 'c-mode-common-hook
     	  (lambda () (c-toggle-auto-hungry-state 1)))
