That Crazy Caret

I am surprised nobody mentioned that '^' has significance to CSH as
a substitute operator.  An example :

% ls -l fobar
fobar not found
% ^o^oo
ls -l foobar
...

And an example of misuse of '^' in the CSH :

% ^sanka
Bad substitute.

I forget what the original symptoms were, but I don't think they would
result from improper use of the '|' symbol.
