hmmm, I am just trying zsh, and I still am having problems.  I cannot
see, so I use speakup or orca to read the screen to me and when I type
the second character of the command line, I hear the first character
again.  I am not sure what is happening, does the cursor move back a
character for a brief period, or what?  Also, the comp systemis very
confusing, its hard to read the list that is produced it seems to be in
columns of some sort and aside from just typing more characters on the
command line, I am not sure what to do.  I will look at your .zshrc, but
a lot of it will not do me any good, so I will read the docs and do
something.
