Re: ins and del

I took a different approach to the same problem. Florida Blind Services has
a business enterprises program - blind vendors of food service facilities.
All managers must be legally blind. A person with low vision did their
minutes that had a policy change using green for additions and red for
deletions. I couldn't change the minutes, but needed to let our speech users
(some actually use windows eyes) have the same information. I used an old
fashion approach, Words.

Here was my disclaimer. You can guess what I did or look at full minutes at

Disclaimer from web administrator: Minutes were modified to ensure people
using speech or people who are colored blind would understand what text was
deleted in the "Selection Process Improvements" and what new text was
replaced. Original text counted on "color only" as an indication of deleted
text. The use of color was kept, but the text such as "the following was
deleted" and where appropriate "replaced with" were added to minutes in the
appropriate places to ensure that everyone could benefit from the details
outlined in these minutes. Context was in no way modified.

This seems to be the approach that is used in the federal register as well.
(without the color that the low vision user liked - just the words, no
disclaimer needed).
