	I'm using debian linux and the lisp files are in
	/usr/share/emacs/site-lisp directory. Some files here are names
	xxxx-el, some just xxxx, and some as xxxx.el, whereas some
	others as xxxx.elc . I don't understand lisp or programming so I dont

	my home directory and inform emacs somehow that this directory
	is in my home dir?

A few mode questions if you or anyone has the time:

How to get yellow color on emacs in console? Yellow always shows up as
   brownish-red.

Why does Emacs load all files in to the scratch buffer? If it's a file,
and we've modified it, emacs asks us to save it before quitting but
doesn't ask any such thing if we've typed in to the scratch buffer.
How to autosave the scratch buffer? Sometimes I jot down something useful,
in to the scratch buffer when there's no time to think of a filename etc.

How to make a custom dictionary and load it in emacs? How to use
   autocompletion for long words in the custom dictionary? How to use
   emacspeak? Do I need to become blind to use emacspeak or can anyone
   use it?

How to print from emacs, in color (with background, foreground and
   syntax-highlight colors)?


Thanks a lot for the detailed replies, thanks to others too who replied.
I haven't been getting any messages on this list sine last 5 days or
more, so please cc me a copy if you reply.

The convention is that Emacs Lisp files are named .el and byte-compiled
Emacs Lisp files are named .elc.  Anything is in your site-lisp
directory is, well, unconventional.

You could move those files to your home directory with the mv or cp and
rm commands, and then inform Emacs like this:

(setq load-path (cons "~" load-path))

You would have to show us what you put in your .emacs file and exactly
what error was reported.

...

Try this and see if you like it:

(add-hook 'text-mode-hook 'turn-on-auto-fill)

...

Each buffer is in exactly 1 major mode.  You can turn on additional
minor modes via the major mode's hook variable, e.g. the text-mode-hook
variable and the turn-on-auto-fill function above.

"auto-save" means something specific in Emacs.  What you want to do is
to associate the *scratch* buffer with a file.  Since your .emacs file
is executed in the *scratch* buffer, try this:

(set-visited-file-name "~/.scratch")

...

M-x ps-print-buffer-with-faces (also available on the File menu bar,
under Postscript Print Buffer).

I redefined C-x C-b to bs-show which is a much better
buffer listing with lots of commands for dealing with
and switching to buffers.  The file bs.el (should be
included with emacs) also includes commands for
cycling the buffer forward and backward, which I bound
to M-n and M-p, they also show a list (in the
minibuffer) of the buffers in the order they will be
cycled through. They ar bs-cycle-next and bs-cycle-previous.
