Open your .emacs file in a buffer and type M-x eval-buffer - you won't
even have to save it. Or at least, that's what I do. And no guarantees
that that will work correctly with all extensions - though it generally
seems to work ok for simple changes.

You can also eval just the bit you've changed by placing point
immediately following the expression in question and entering C-x C-e.

Most changes can be evaluated right there, in the buffer that you have
opened to edit your ~/.emacs file.  If you have changed the default
value of a variable:

    (setq-default diff-switches "-u")

You can move past the closing parenthesis, and type `C-x C-e'.  This
will evaluate the expression, and you are done.

If you are adding a new hook to text-mode

    (defun keramida-text-mode-hook ()
      (setq fill-colum 72))
    (add-hook 'text-mode-hook 'keramida-text-mode-hook)

You can mark the two expressions, and type `M-x eval-region'.  The
expressions in the current region will be evaluated, and immediatelly
apply to any new text-mode buffers that you open.

There _are_ a few exceptions, i.e. some of the changes to `customize'
stuff are trickier to evaluate directly in the buffer that edits your
~/.emacs file.  If you are making this sort of change, I'm sure some of
the experienced Emacs hackers who hang out here can help :)

How about M-x load-file

and then specify ~/.emacs as the file to load?

I use this function:

;; reload the init file 
(defun reload ()                                         
  "Reload the .emacs file" 
  (interactive "*" )
  (load-file ".emacs"))

HTH,
Rob

The current directory may have changed since Emacs started.  A minor
improvement is probably:

    (load-file user-init-file)

The `user-init-file' contains the absolute path of the user's init file.
If the actual init file loaded is a compiled file, such as `.emacs.elc',
the value refers to the corresponding source file, so the `load-file'
call will DTRT regardless of the current working directory.
