Re: A question. Colors in Shell and Lynx



Hello all:

OK.  My thanks to Bart Bunting.

I rewrote the alias line for ls in the .bashrc file on Adam's machine and 
was able to correct the problem.  Although I see that this same line exists 
in my own .bashrc file, and that file names are rendered in color -- both 
when running ls from a shell and from an emacspeak shell, whether at a 
console or when invoked from an X session -- these spurious characters do 
not show up, nor are they spoken when I run an ls command on this 
machine.  I don't understand why.

But the follow up and I suspect related question which motivated this post 
is:

I get the same spurious characters in lynx.

cat /etc/lynx.cfg | grep color
yields a commented out line:
#ENABLE_LYNXRC:show_color:ON

but no lines with "color" included which are not comments.

As a sighted user who uses emacspeak generally only to support my friend 
Adam's learning curve, is there some way I can create an alternate lynx.cfg 
file which would be invoked when I launch lynx from inside emacspeak that 
would turn colors off, but which would stay out of my way when I'm working 
from a shell at a visual console?

Given that the line I thought would turn color on seems to be commented 
out, how is it I would turn colors off?

And also somewhat related, I'm working to rebuild our state Party's web 
site and have been studying cascading style sheets.  I see that I can tie a 
.css file to the media type used to render an .html page.  Are there any 
recommended models I could use as my standard .css for aural browsers?

I'd love to do what is possible to make our web site fully 
accessible.  Coaching Adam with w3c and lynx showed me that vast portions 
of our existing web site are inaccessible to the blind.

Thanks in advance for any clues.
