Completion- Help

Completion- Help

[FD]

Hi,
I'm trying to use etags to create a Tags file containing a list of words 
so I can use the completion using this list of words.
I put in my .emacs.el this :
(setq tags-table-list '("c:/Program Files/emacs/bin/" ))
(global-set-key [C-tab] 'dabbrev-expand)

(I'm using Windows XP)

My question is how to write the regexp (I'm a newbie) to retrieve the 
words from a file. The file contains only a list of words separated by 
spaces.

I tried
etags -l none -r="[a-zA-Z0-9]+" list.txt
but I obtained this:
etags:  [a-zA-Z0-9]+  :unterminated regexp.

What's wrong?
What should I write?

Where can I find a good documentation on regexps for emacs?

I would like to color only some words in a text (contained in this 
list). Is there an easy way to do this?

Many Thanks

the man page for etags has examples for how it expects a regex to look
like: they have to delimited by slashes.

i don't know if etags' regexes use the same syntax as emacs' regexes,
but they look similar ("basic regular expressions"). 

in general, the info documentation for emacs is excellent. you can
read about regexps here:

     (info "(Emacs)Regexps")

(copy this line into some emacs buffer, put the cursor behind the last
parentheses, and press C-x C-e). 

hope that helps,
