-- a bunch of useless stuff about moving the pipe to shift-del

OK, I was pretty cryptic in my previous message.  In short, I found the
delete key entry in a keymap and and posted it's location.  I got several
responses requesting info on how to actually change it.  

Below is source to a quick hack that reads a keymap on stdin and changes the 
shift-del character to one given on the command line.  To run, compile
this and run "a.out '|' </NextLibrary/Keyboards/USAkeymapping >new.keymapping".
Move new.keymapping to ~/Library/Keyboards, /NextLibrary/Keyboards or
/LocalLibrary/Keyboards, restart Preferences and it will appear in the list
of keyboards.

If anyone needs a compiled copy of this, send me mail and I'll email
a uuencoded copy to you.

Cheers,
