Glad to be of service. I had a KnightRider gag too, but I removed it at the
last minute ;-)

It's just the ASCII backspace character. I used to know all of the ASCII
control characters off by heart once, but I can't recall many now. I
remember that '\x07' is BELL - I use that one often. I have a small program
called 'beep' whose sole purpose is to output a single BELL character. I use
this to notify me when something is done in the shell so I can switch away
and work in another window, e.g.:

    % make all ; beep

I'm sure if you do a google on "ASCII control characters" you'll turn up a
table somewhere.
